The Schrödinger's Cat Conundrum - What Really is in the Box?

Stretching the Schrödinger’s cat thought experiment analogy – the IET Archives recently received a small box that supposedly contained a ‘permanent detector’ a component that was used in connection with crystal radio sets of the 1920s. A permanent detector made by the company Radio Instruments (RI), made by the company between 1922 and 1930, was what was advertised on the box – but was that really the item that could be found in the box?

Well there was something in the box and it looked a little like the illustration on the outside of the box, but it was definitely a different object. Upon very careful examination, in a certain light, at a certain angle, the faint lettering ‘Brownie Permatector’ could be found.

This item was nothing to do with the eponymous dessert square, developed in the US at the end of the 19th century, but instead a permanent detector made by a rival firm to RI called the J W B Wireless Company (Brownie was a brand name). Both companies manufactured permanent detectors for crystal radio sets in the 1920s. The Brownie permanent detector found in the box, which the company introduced in 1926, is shown below.

 

 

The crystal radio receiver, or crystal set, contained a .cat’s-whisker detector, an electronic component consisting of a thin wire that gently touches a crystal of semiconducting mineral. The Brownie permanent crystal detector shown above comprises a nickel-plated housing with a crystal and whisker inside the housing. The whisker could be fixed permanently at a sensitive point on the crystal hence the term ‘permanent detector’.

Given the above, we now have evidence of one reality in answer to the Schrödinger cat conundrum. What is inside the box – it is a cat’s whisker!

Electrical Technical Papers of the 1950s and Radio Objects from the 1920s/1930s

The IET Archives recently received a donation of electrical technical papers, dating primarily from the period 1949 to 1955. These papers were amassed by Edward J Back when he was working as a Technical Assistant in the 1950s for the Consulting Engineering Department of the Company Johnson & Phillips. Edward Back was a Graduate member of the IEE before becoming an Associate Member in 1953. This collection has been catalogued with the reference SC MSS 262.

Whilst many of the papers and articles were from journals that can be found in the IET Library such as ‘Distribution of Electricity’, ‘Electrical Times’, ‘The Electrical Journal’ and ‘Electrical Review’, these readily available articles were interspersed with letters and memoranda typically written by S Austen Stigant the Technical Adviser at Johnson & Phillips. The papers are organised by subjects including cables, electro-technology, rotating machinery, transients, and transmission.

The subject matter is understandable given that Johnson & Phillips was a cable making and wire rope machinery company founded in 1875 which by the 1950s had become a specialist in the area of transmission transformation and control of electricity. It manufactured electric cable, cable accessories, switch gear, transformers, capacitors and overhead line materials. It was acquired by the Delta Metal Company in 1964.

The collection is a useful addition to the IET Archives technical collections, particularly because the collection includes brochures and publications of other companies involved in the manufacturing of electrical equipment such as the English Electric Company, British Insulated Callender’s Cables (BICC), and Ferguson Pailin. The illustrations below are from a BICC publication from the early 1950s for its power capacitors which show a layered section diagram of its automatic power factor correction equipment for capacitors.

Radio Objects from the 1920s/1930s

As is quite often the case with collections of papers formed by individuals, some small objects, related to the individual are donated along with the papers. In this case Edward Back was likely to have been a radio enthusiast because the collection included a radio microphone dating from the period 1935-1940, inductors used in radios (coils of wire wrapped on a Bakelite core), and a permanent detector used in crystal radio sets from the 1920s.

The Telsen Electric Co (1935) Ltd ‘Ace’ spring-suspended microphone (type 68) is shown below;

 

 

 

Telson Electric Limited was a British firm that made a spring-suspended microphone (Ace brand) from 1930 to 1939. The company, founded by A Macnamara, based in Birmingham was active from 1924 to the 1940s, and manufactured wireless broadcast receivers, components, microphones and construction kits. It was founded by A Macnamara and had a cabinet making department which made the furniture into which the wireless receivers were built. It purchased Bakelite cases from Edwin Elliot of Birmingham; produced components for the building of a home wireless receiver, and produced blueprint layouts for home construction. The company went into receivership in 1935 but was then bought out of receivership. After this the company traded as The Telsen Electric Company (1935) Limited.

Telsen microphones were used for both home recording and public address. The Science Museum has a Telson microphone in its collection but that is a different model, likely to be a model 58, rather than the microphone above which is a model 68. Here is a link to the model in the Science Museum collection. Telsen Ace microphone at Science Museum.

The Education and Training of Engineers Born Between 1915 and 1925

The subject of the training and education of engineers has been a topic very dear to the hearts of the members of the IET and its predecessor organisations for decades going back to the 19th century. These subjects appear time and again in the minutes of these organisations such as within the IEE’s Council minutes. Material on education and training can also be found extensively throughout the other, non-organisational collections, found within the IET Archives such as the papers of Sir Arthur Fleming (NAEST 70) who established a trade apprentice school at what became Metropolitan-Vickers.

Training and availability of engineers has been an issue that many governments have sought to address and concerns have resulted in many significant reports such as ‘Engineering Our Future’, known alternatively as the Finniston report, published in 1980, and shown below.

 

 

The subject remains very topical and when EngineeringUK’s report, ‘Engineering UK 2015: the state of engineering’, was published earlier this week, it received widespread media attention

http://www.engineeringuk.com/Research/Engineering_UK_Report_2015/.

Given this background the IET Archives has been fortunate to receive a recent donation of questionnaires and related correspondence which was the output of a project undertaken in 1994 and 1995 to look at the education and training of engineers born between 1915 and 1925.

The 1994/1995 Survey of Engineers

Dr Colin Hempstead, an academic at the University of Teesside, carried out a survey in 1994, targeting engineers who had been born between 1915 and 1925. Dr Hempstead sought participants via 'IEE News' in 1994 and via other channels such as the 'Newcomen Bulletin'. He asked engineers born between 1915 and 1925 to complete a survey questionnaire about their education and training. The questionnaire was very detailed and asked questions under the categories of; personal details; education; qualifications; training, funding of education and sociological information such as mother’s and father’s occupation, reasons for leaving school and reason for becoming interested in engineering.

Many of the respondents provided additional personal histories and biographical information to supplement the completed questionnaires. Whilst the survey was not exclusively aimed at the Institution of Electrical Engineers and its members, the majority of completed questionnaires came from IEE members from who circa 150 replies were received.

This detailed information on the educational and training background of engineers in the first half of the 20th Century is likely to be a very useful and valuable resource for researchers in the future but they will have to wait for several more decades before these records are made available for open consultation.

As this collection contains detailed personal information on individuals who provided this information relatively recently in 1994/1995 the files will remain closed to researchers in the short to medium term in line with the IET Archives’ closure policy in respect of collections containing personal or sensitive information. Using extracts of information from the collection, where individuals cannot be identified from the information provided, would be possible in the intervening period.

This new deposit has been catalogued as SC MSS 261, although the catalogue entries do not mention the name of individual respondents to preserve anonymity until the closure period has expired.

Oral History and Papers Related to the H W Sullivan Instrument Company

The IET Archives recently received a donation of cassette tapes and notes relating to an oral history project carried out in the late 1990s. These items have now been catalogued as NAEST 221 and the audio cassette tracks have been digitised.

The oral history project recorded interviews with several people who were intimately involved with H W Sullivan, the noted British instrumentation company, which began life in 1897 and was taken over by Cambridge Instruments in 1967. Cambridge Instruments was itself taken over by George Kent and then Thorn. In 1972 Thorn, which ultimately became Thorn EMI, moved the manufacturing of Sullivan products from Orpington, Kent, to its Dover, Kent, site where Thorn was already manufacturing instrumentation under the AVO brand. The Sullivan brand was maintained for a period and was still being used in the early 1980s. H W Sullivan was known for its precision test equipment and measuring instruments such as Wheatstone bridges and galvanometers. An H W Sullivan product is illustrated below, taken from a telephone cable testing equipment catalogue circa 1955.

 

 

The product below is one of the last products with the Sullivan brand name and comes from the late 1970s.

 

 

The donation was particularly welcome because the IET Archives already has an extensive collection of instrumentation material. Collection NAEST 145 comprises the trade literature and technical manuals of AVO International Ltd including its predecessor companies such as, Thorn EMI Instruments Ltd (renamed Megger Instruments Ltd in 1987), Evershed and Vignoles, and of course H W Sullivan. The HW Sullivan element alone of NAEST 145, mainly technical literature and manuals of the 2nd half of the 20th century, fills 9 archive boxes. 

Brief Chronology for H W Sullivan

1856 Herbert Watson Sullivan born in Malta.

1870 H W Sullivan apprenticeship with Telegraph Construction & Maintenance Co Ltd.

1873 H W Sullivan joined Eastern Telegraph Co, Gibraltar.

1878 H W Sullivan became an Associate Member of Society of Telegraph Engineers (STE).

1879 H W Sullivan joined Telegraph Construction and Maintenance Co Ltd.

1892 H W Sullivan became a Member of the IEE (formerly STE).

1893 H W Sullivan granted galvanometer patent.

1895 Donald Arthur Stevens born.

1897 Company H W Sullivan formed; offices at 19 Gt Winchester St; works at Old Broad St.

1914 Works address changes to 104-6 Middlesex St.

1921 Donald Stevens BSc (Civ. Eng.) at KCL, goes to Africa.

1922 The company HW Sullivan Ltd formed with DA Stevens, Lt Commander Walter George Bishop & James Hayne Stevens.

1925 Herbert Sullivan dies and Donald Stevens takes charge.

1927 Company factory moves from Middlesex St (Petticoat Lane) to Leo St, Peckham.

1963 Company factory moves to Murray Road, Orpington.

1964 Donald Stevens retires, with his sons Brian and David Stevens taking over.

1966 Donald Stevens dies.

1967 Company taken over by Cambridge Instruments.

1968 Company taken over by George Kent, with Bill Goldfinch as General Manager.

1970 Company taken over by Thorn.

1972 Thorn moves manufacturing of Sullivan products to Archcliffe Road, Dover site with AVO.

 

 

1980s Possibly the last use of the Sullivan name in advertising.

The H W Sullivan Interviews

The interviews were typically around 90 minutes long and took place with the following five individuals (summary transcripts of the interviews were made at the time of the recordings);

1. Mrs Mabel Stevens, widow of Donald Stevens. Donald Stevens ran the company from 1925 until 1964, taking over the running from Herbert Watson Sullivan.

2. Mr David Stevens, son of Donald Stevens, who jointly took over the running of H W Sullivan from his father in 1964. Donald focuses particularly on the subject of sales.

3. Mr John Lewis who covers the topic of the H W Sullivan office and personnel.

4. Mr Chris Jones who covers the subject of resistance testing.

5. Mr Bill Goldfinch who deals with the subject of the Cambridge Instruments takeover in 1967. Cambridge Instruments was taken over by the George Kent Group in 1968 to form the largest independent British manufacturer of industrial instruments. The George Kent Group was itself taken over by Thorn in 1970. Bill Goldfinch was the General Manager of George Kent Group.

In addition to providing very detailed accounts of the operations of the company, its staff, the competitive environment, and the company’s financial performance, the interviews give some fascinating insights into British industrial and social history.

Mr Jones talks of joining H W Sullivan in August 1941 at the age of 13. At that time the company was “in the hands of the bank who put in Mr Burrows as Manager”. When he was being interviewed in July 1941, he was told he could start on August 4th and when he protested that he would not be 14, the minimum age for work at that time, he was told, “if you want the [expletive] job you start on Tuesday”.

Mr Lewis tells a different story from the war period, “we weren’t used to people walking around without their coats on, they didn’t do it. Mr Stevens always came in a black coat, waistcoat, and black striped trousers. I remember during the war my mother bought me a pink shirt with a Trubenised [brand name] collar at the market, and at five past nine I was on my bike back home to change into a white shirt with stiff collar having been asked didn’t I realise you only wore coloured shirts on Saturday.”

The digitised audio files for NAEST 221 can be consulted in the IET Archive Centre. Details for visiting the Archive Centre can be found on the archive web pages here http://www.theiet.org/resources/library/archives/archives-contacts.cfm .

IET Archives 16mm Film Digitization Project

The IET Archives has just completed a project involving the digitisation of some of its 16mm film collection, a project which has been running throughout 2014. 34 films, none of which had previously been converted to other formats, and had therefore been unavailable to view within the IET for several decades, have now been digitised. Browse versions of these films are now available in either .mov or .mp4 formats for viewing on computers and other devices or alternatively they can be copied to a DVD format if required by enquirers. The IET Archives also holds these films in an uncompressed file format for long-term preservation purposes.

The majority of the films digitized, date from the 1930s to the 1950s, and are short 7-10 minute films of individuals who had been awarded the IEE’s Faraday Medal or who had been made IEE Honorary Members. Most of these films were made specifically for the IEE, following a particular award. The still below comes from a film made in 1934 of Sir John Ambrose Fleming, 7th recipient of the Faraday Medal, when it was awarded by the IEE in 1928. Fleming, who invented the thermionic value in 1904, was aged 85 when he took part in this film.

The film was a British Thomson-Houston (BTH) Electrical Recording. BTH was founded as a subsidiary of the General Electric Company of the US but came into British ownership when it was amalgamated with Metropolitan-Vickers in 1928 to from Associated Electrical Industries (separate BTH brand identity remained until 1960).

 

 

The image below is from another of the digitised films but is a little different in that is a General Electric Company film, made in the US in 1932. The film is of Professor Elihu Thomson who was the 6th recipient of the Faraday Medal when it was awarded by the IEE in 1927. In the film Thomson, the person shown on the left below, talks about the merger of the Thomson-Houston and Edison companies to form GE, his life, and also his inventions (Thomson took out 700-800 patents).

 

 

Elihu Thomson (1853 to 1937) although born in Manchester in 1853, moved with his family to Philadelphia in 1858. Together with Edwin J Houston he founded the Thomson-Houston Electric Company in the US in 1883 which was one of the precursors of the General Electric Company of the US which was formed in 1892. The GE film above was an RCA Photophone recording and the interview was carried out by Thomson’s friend, Edwin W Rice Jr, Honorary Chairman of GE at that time, on the lawn of Mr Rice’s home in Schenectady, NY.

The frame above shows a steam train passing by in the background, the sound of which can clearly be heard on the film. This is quite appropriate given that Thomson talks on the film about the development of the railways amongst other things.

Film from the 1920s – BTH’s Work on Sound on Film

The 16mm digitisation project also included two early 20th century films that were donated to the IET in 2013 from a former BTH employee. One film (without sound) from the 1930s is of the production by BTH of its well-known Mazda branded light bulb and shows the complete process of manufacturing, packaging and distribution at its factory. A still from that film is shown below.

 

 

The second film (again without sound) is another BTH film, this time from the 1920s, and shows the company’s work on developing films with sound (the technology for synchronizing electrically recorded audio to a picture image on a commercial basis was developed by several competing companies in the US and UK in the late 1920s).

 

 

Coincidentally the IET Archives has several collections containing BTH material, in particularly a collection referenced as NAEST 74. NAEST 74 is a very large group of photographs and glass plate negatives of early BTH sites, equipment and manufacturing processes and installations, primarily covering its Rugby factory. It covers 28 albums and 13,000 glass plate from the period 1898 to 1939. The company products included induction motors, alternators, switchgear, turbo-generators and turbines, as well as a large number of rotary converters and motor converters, primarily for chemical plants. In the period before the First World War, BTH manufactured most of the equipment for railway electrification in Britain and equipped more than fifty tramway systems. In addition the company carried out a great deal of work for the new London Underground lines.

In the New Year the IET Archive online catalogue will be amended for those 16mm films that have been digitised to make it clear that digitised versions of the films are available. Anyone interested in a copy of the digitised films should contact the IET Archive Centre via phone on 020 7344 8407 or via e-mail using archives@theiet.org.

Peter J Baxandall Condenser Microphone Papers

A file of papers recently deposited with the IET archives contained over 40 years’ worth of primarily technical notes, thoughts and ideas on the subject of the condenser microphone written by the audio and electronic engineer Peter J Baxandall. The notes cover the period from the early 1950s to the early 1990s. The condenser microphone, also known as a capacitor microphone or electrostatic microphone, was invented at Bell Laboratories in 1916 by E C Wente. Two images of a condenser microphone from amongst the Baxandall papers, probably of experimental models taken circa 1965, are shown below.

 

 

 

Baxandall (1921-1995), wrote a chapter on electrostatic loudspeakers for the 2nd edition of the Loudspeaker and Headphone Handbook, 1994 that is sometimes referred to as the seminal work on the subject. However, he had already gained significant attention in the early 1950s for his bass and treble circuit or tone-control circuit about which he published details in Wireless World, October 1952, and which was used in hi-fi audio systems.

Biographical Details for Peter J Baxandall

Peter Baxandall, born in 1921, was educated at Kings College School in Wimbledon before going on to study electrical engineering at Cardiff Technical College, Wales. He graduated with a BSc (Eng) in 1942.

Following graduation Peter spent two years as a radio instructor for the Fleet Air Arm before joining the Royal Signals and Radar Establishment (RSRE), based at Malvern, where he began work in the Circuit Research Division. He worked for the RSRE until his early retirement in 1971. After that Peter continued to work as an electroacoustical consultant.

Projects on which Peter worked as a consultant included; audio-frequency transformers, radio-frequency carrier microphones, powered loudspeakers, dipole and electrostatic loudspeakers, loudspeakers with motional feedback, bandbass loudspeakers, oscillators, high-speed tape-duplicating equipment, and high-precision microphone calibration methods.

Peter was closely associated with the Audio Engineering Society. He became a Fellow of the AES in 1980 and was awarded its Silver Medal in 1993 which is given in recognition of outstanding development or achievement in the field of audio engineering. Peter died in 1995 and an 'in memoriam' tribute to him was published in the Journal of the Audio Engineering Society, vol.44 no.9, September 1996.

Collection Contents

For anyone with a technical interest in microphones there are dozens of Baxandall’s handwritten notes detailing his experiments, ideas for solving problems, and thoughts and comments on published technical literature. The note titles, written in the first half of 1965 are shown below as an illustration of the types of material to be found.

'Data from advert by International in Journal of the AES', dated January 1965.

'Circuits of transistorized rf condenser microphones', based on article in the January 1965 issue of the Journal of the AES by H J Griese.

'Thoughts re tension and diaphragm in cardioid condenser microphone', dated April 1965.

'Thoughts on what should be done about rf microphone system', dated 19 May 1965.

'Design of miniature pressure capsule', dated 9 June 1965.

'Own thoughts on cardioid capsule theory', dated 19 June 1965.

Peter’s technical notes are interspersed with correspondence with microphone manufacturers, orders for materials for his experimental equipment, and discussions with others who had an interest in the field. It is interesting that there are several notes on the subject of Reg Williamson’s condenser microphone capsule because ultimately this file of material passed to Reg Williamson upon Peter’s death – there is a letter with the deposit dated 1996 (the year after Peter’s death) in which Reg recalls the visit to Peter’s house when he picked up this file of material on condenser microphones. Reg also recalls leaving ‘a vast amount of paperwork’ which he expected to be dumped.

The Peter J Baxandall papers have now been catalogued (reference SC MSS 260) and are available to view in the IET Archives. The contents of the collection can be viewed in the IET Archives online catalogue.

Discover your engineering past at the IET Archives
Engineering history is rich and varied, full of innovation and pioneering achievements. The IET boasts some of the world's most famous electrical engineers, responsible for the creation of the telegraph, telephone and the revolution of the distribution of electrical power. At the IET Archives we are fortunate to have personal papers of individual engineers and corporate records that chart these developments. If you are interested in a particular aspect of engineering or tracing your family tree the collections within our archive can be an invaluable source.


Image of Oliver Heaviside and his family.

This blog has been written to promote the launch of our new family history leaflet. It supplements what you can find in the leaflet and on our website under the family history section.

Our heritage
The IET was founded in 1871 as the Society of Telegraph Engineers but through an amalgamation with the Institution of Incorporated Engineers in 2006 our predecessor institutions date back to 1854. The Society of Telegraph Engineers began as a learned society for those involved in the electric telegraph industry but to keep up with technological developments of the time it changed its name to the Institution of Electrical Engineers in 1889. Since then the IEE amalgamated with the Institution of Radio Engineers (IERE) in 1988 and the Institution of Production Engineers (IMfgE/IProdE) in 1991.

It's a family affair
If you are researching your family history or the life of an individual we may be able to help you with some details concerning their profession. Although the term 'electrical engineer' in the nineteenth century did not denote affiliation with a professional organisation if you see the post nominal MIEE (Member), AMIEE (Associate Member), or FIEE (Fellow) then they were members of the IEE.

Our membership application forms from 1871-1901 can help fill in the gaps about an individual's employment, education and social circles. The printed lists of members from 1871-1997 can trace geographical movement as well as mobility through the membership categories. It is now possible to browse a list of members from 1871-1930 online, view the full record and download an image of the original thanks to a partnership with Ancestry.co.uk

Part of this project was to digitise over 170,000 electrical engineer records. Records were selected and scanned on site at Savoy Place, London, using the most current scanning technology to produce high quality images. These are now fully searchable by name, date of birth, location and date of application. For more information on how to access these records please visit our family history section of our website

Other records to help further your study
If the person you are researching was not a member of our Institution we can still help by looking through the Electrical Trades Directory (known as the Blue Books) published from 1883. Within these pages are information on electrical firms, advertisements and an alphabetical classified section on individuals. We also have some other institutional records from the IERE, IProdE and IIE.

Occasionally an obituary or biography may have been written about certain members and published in the Journal of the Institution of Electrical Engineers (JIEE) or in the Blue Books directory.

In addition to paper records we also have some photographs, portraits and films of notable engineers. These include past Presidents, Faraday Medallists and Honorary Fellows.

Our military records can help to learn more about an engineer's role during the two world wars. Some contain biographical information such as the First World War Roll of Honour, which holds details on the member, where they were stationed, military action and how they died.

We also hold a number of interesting collections relating to women in engineering and science, education and the importance of domestic electricity.

Contact us for some advice

If you would like to know more about our records please visit our family history pages on our website or see our new family history leaflet.

This leaflet was produced to highlight the varied collections we hold that may help with family history research. We want to reach new audiences to open up our collections and to assist those who are embarking on their family history with an engineering aspect. The images chosen illustrate the range of material we have to offer.

If you have any enquiries regarding your research please contact us for a chat, we are always happy to help.

James H H Merriman Papers - President of IEE 1974-75

The IET Archives recently received a donation of papers belonging to James Henry Herbert Merriman who was the IEE President in 1974-75. The photograph above is the IEE’s formal black & white photograph of James taken at the start of his Presidential term. Perhaps surprisingly the IET Archives has very few collections of former IET/IEE Presidents who held that position after the Second World War so this collection was very warmly received.

Biographical Details for James H H Merriman

James Merriman was born in Pembroke, 1915. He was educated at King's College School, Wimbledon, and King's College, University of London. He obtained his BSc (Hons) in 1935 and did postgraduate research at King's College London obtaining his MSc in 1936.

James entered the GPO Engineering Department, Radio Research Branch, Dollis Hill, in 1936 and was associated with the development of long distance radio communication systems. From 1940 to 1948 James was Officer-in-charge at Castleton radio research station. From 1948 to 1953 he worked as Engineer-in-Chief, GPO London HQ on HF, VHF and microwave system development and planning.

In 1954 James went to Imperial Defence College and in 1955 he became Head of GPO Engineering Department O&M unit. From 1956 to 1959 he was Deputy Director Organisation and Methods Division, HM Treasury. He then became Assistant Engineer-in-Chief GPO with oversight of all transmissions including space systems in 1963, becoming Deputy Chief Engineer in 1965, Senior Director of Engineering in 1967, then Senior Director, Development.  Eventually James became Board Member for Technology 1969-1976. Other positions James held included Chairman National Computing Centre 1977-1983 and he was a member of the NEDC Electronics Committee from 1977-1983.

James who received an OBE in 1961 and his CB in 1969 was Faraday Lecturer 1969-1970, was made a Fellow of King's College in 1972, received an Honorary DSc from Strathclyde in 1974, became President of the IEE in 1974-75 and was made an Honorary Fellow of the IEE in 1981.

When James completed his term in office as IEE President, as was customary at that time, he received a certificate of thanks from the IEE Council which was signed by a Council member, and the new incoming President. James’ certificate is shown below.

 

 

Collection Contents

The deposited collection comprises primarily James’ published papers and articles, annotated typescript versions of lectures and a small number of photographs.

There are some nice black & white photographs from the 1969-1970 Faraday lecture. This was given by James on the subject of ‘people, communications and engineering’. The lectures were given around the country and took place over many weeks. The two photographs below show James on stage at one of the lectures and then the two GPO vans that were required to transport all the equipment need to support the lectures.

 

 

 

The James HH Merriman papers have now been catalogued (reference SC MSS 259) and are available to view in the IET Archives. The contents of the collection can be viewed in the IET Archives online catalogue.

Restoration of Portraits Hanging in the Lecture Theatre at Savoy Place

The eye-catching wood-panelled lecture theatre at the IET’s Savoy Place in London has been enjoyed for many decades by IET staff who worked there, attendees at events hosted at Savoy Place and general visitors to the building. However, many of those who have passed through the doors of the lecture theatre may not have been aware of the history of the eight portraits that have hung on the walls, or the people represented in those portraits.

The two images below show the lecture theatre at two different points in its history. The first image is from the 1930s shortly after the portraits were hung for the first time – note that the portraits are framed and hung on top of the wooden panelling. The second image is much more recent and dates from after the major refurbishment of the lecture theatre which took place in 1959-60 (when the paintings were mounted in recesses behind the panelling and also lit) and after the 1990s installation of the ceiling design by artist Tony Raymond.

 

 

 

Who Are the People Shown in the Portraits?

The eight portraits that were hanging in the lecture theatre in early 2014 were of the following well-known people; Sir Joseph Wilson Swan; Lord Kelvin; Sebastian Ziani de Ferranti; Michael Faraday; Alexander Graham Bell; Andre Marie Ampere; John Hopkinson; and Alessandro Volta. Images of two of the paintings following their recent restoration are shown below. They are firstly Michael Faraday, painted by George Harcourt in 1926 and secondly Alessandro Volta painted by Giuseppe Palanti in 1928.

 

 

 

How Did These Particular Portraits Find Their Way Into Savoy Place?

The IEE Council minutes of 1925 show the beginning of the discussion about oil paintings for the lecture theatre. It is probably no surprise that there was much debate about who should be represented in the portraits, who should be commissioned to paint the portraits, and which images of the chosen subjects should be used as the basis for the new portraits.

The first two paintings agreed upon were Faraday and Kelvin both to be painted by Mr G Harcourt ARA for a fee of 400 guineas for each painting. What is perhaps surprising is that the IEE only commissioned and paid for one of the portraits, that of Kelvin. The portrait of Faraday was commissioned by Mr Evershed and then immediately presented to the Institution as a gift. This was the pattern set for the subsequent paintings. Each was commissioned and paid for by a noted member of the IEE and then donated to the IEE. This situation meant that the commissioner of each painting had a significant influence over the subject matter and painter of each portrait. The portraits of Faraday and Kelvin were completed and hung in 1926.

In 1927 a short-list of 6 names for the remaining paintings was noted in the IEE Council minutes. That list included Volta, Ampere, Hopkinson, Bell and Swan all of whose portraits were painted over the next few years. However, the name of Gilbert dropped off the list to be replaced by de Ferranti. Mr Paul donated the Volta painting, Sir Charles Parsons donated the Swan painting, Sir Tom Callender donated the Hopkinson painting, Mr Garcke donated the Ampere painting, Sir Hugo Hirst donated the painting of Bell, and Mr Marryat donated the painting of de SZ de Ferranti.

A 9th and a 10th painting, one of Charles Wheatstone and one of James Clerk Maxwell, were also commissioned as part of this process. However, despite the paintings being produced, they do not appear on the walls of the lecture theatre in the 21st century although the portraits do still exist and are in the IET’s portrait collection.

The Recent Restoration

As part of the process of redevelopment of Savoy Place, the lecture theatre paintings were taken down in early 2014, which involved carefully removing some of the panelling to extract the individual paintings. This opportunity was used to send the 8 lecture theatre paintings to a fine art restorer to clean and restore any damage to the paintings which had been in situ for many decades. This process was completed a few months ago and the paintings are now crated and in storage awaiting their return to Savoy Place in 2015.

Bernard Martin Crowther (1910 - 2005) - Editor of Science Abstracts for Almost Two Decades

Earlier in 2014 the IET Archives received a donation of papers belonging to Bernard Martin Crowther. Bernard Crowther was intimately involved with the history of the IET, particularly the IET’s Inspec database, where he was the Chief Editor from 1945 to 1964 of what was then known as Science Abstracts.

The history of Science Abstracts and Inspec is recorded in detail on the IET Archives web pages here http://www.theiet.org/resources/library/archives/inspec/index.cfm. Bernard Crowther is mentioned in passing on those pages in the section covering Inspec staff memoirs where the recollections are recorded of two Assistant Editors who worked for Bernard, the well-known author Sir Arthur C Clarke, and Gerald Beck.

Bernard’s papers which include extensive records of instructions and notes for abstractors, commentaries on the role of abstracting, and details of the changing face of the office in the mid-20th century, such as the introduction of typewriter composition, are therefore a very welcome addition to the archive collections.

Bernard Crowther’s Life Outside of Science Abstracts

Bernard M Crowther was educated at Oundle School, near Peterborough 1924-1929, then at Clare College, Cambridge, 1929-1932, where he studied in the physics faculty, and was taught by the eminent physicist Ernest Rutherford. He worked at Cambridge's Cavendish Laboratory from 1932 to 1935 and was awarded a PhD in 1936 for his work on 'the separation of isotopes'.

Prior to joining the IEE in October 1945 as Editor of Science Abstracts, from 1936 to 1945 Bernard was a researcher at EMI in Hayes, Middlesex. This was an important period in the development of high-definition television in which EMI was a major player and Bernard worked as a junior colleague with the noted electronics engineer Alan Blumlein.

Between 1943 and 1947 Bernard wrote scripts for a 10-minute BBC World Service programme which included reviews of new issues of Nature and Discovery. This interest in ‘reviewing’ then extended further with an invitation from The Economist in 1947 to write physical science book reviews for the journal. This began an 11-year relationship between Bernard and The Economist and many of his book reviews, written between 1947 and 1958, are included in his papers.

Office Life in the 1950’s and 1960’s

Whilst it might be expected that Bernard’s papers would contain extensive details about abstracting and the world of abstracting, it might be less expected that they would contain a detailed record of office life in the 1950’s and early 1960’s. He kept a work diary and also a memoranda copy book covering the period 1955 to 1963 in which minute details are kept of working arrangements in the office and in which the memoranda to his staff are recorded. The formal nature of the office is perhaps exemplified by the following two memoranda:

Memorandum to a Mr Anderton dated 13 September 1960, “Please supply Mr Lever of Science Abstracts with one Comet stapler to replace one evidently removed from his desk illicitly during his holiday. B M Crowther.”

Memorandum dated 27 April 1960, “congratulations – since 4th March you have kept up a pretty steady average of 16 pages per day – actually, allowing for Easter, you are just 32 pages short of the exact average, counting sheets actually sent off. Please keep this up….  BMC.”

The Launch of Tetra Pak in 1951

Another surprising ‘find’ amongst Bernard’s papers was a folder of publicity material from Tetra Pak on the launch of its innovative product in 1951 which had been sent to Science Abstracts. Tetra Pak, a subsidiary of the Swedish firm Akerlund and Rausing, was formed in 1951 just prior to the public launch of its ‘revolutionary new one-way package for milk, cream, auto-oil, fruit juices and ice cream’. Two of these marketing images showing the new product and the novel way of storing multiple packages are shown below.

 

 

 

Life After Science Abstracts

Bernard gave up his executive responsibilities with Science Abstracts in 1964 although he continued to have an association with it for a few more years, first as an Advisory Editor and then as a consultant. His interest in science, technology and physics did not diminish and within his papers is a set of correspondence from 1981 between Bernard and the Head of Documentary Features at the BBC, Will Wyatt. Bernard had heard that a documentary was planned covering the launch of the BBC’s first high-definition television broadcasting service from Alexandra Palace in 1936. He was concerned about potential inaccuracies in the coverage of the efforts of the EMI research team and wanted to speak to the producer to ensure the accuracy of the documentary. Bernard stated, “I was a member of the research team at EMI at the time of the inauguration of the service, and knew all the principal participants at the EMI end quite intimately”. Bernard also wrote a manuscript list of names of the principal participants which he stapled to the set of correspondence.

The Bernard M Crowther papers have now been catalogued (reference SC MSS 258) and are available to view in the IET Archives. The contents of the collection can be viewed in the IET Archives online catalogue.

IET Archives - Rare Books Back From Storage

When the new IET Archive Centre was opened earlier in 2014 at Savoy Hill House there was an initial period when the new strongroom remained empty to allow the environmental conditions to stabilise. Following that period the core archive collections were brought back from storage – those collections that were deemed to be especially valuable or popular. Whilst this process was completed by the summer of 2014, one large gap remained on the strongroom shelves. This was the area allocated to the IET’s collections of rare books particularly those collections known as the S P Thompson rare books library and the Ronalds library.

As the rare books, many bound in leather or vellum, and many of them dating back several centuries, are particularly sensitive to conditions, such as the relative humidity, it was decided to postpone bringing back these rare books until there was a track record of stable conditions through both the colder spring months and also the warmer summer months. Now these collections of rare books have also been returned from storage and sit on the shelves of the archive strongroom. The image below shows the rare books on the strongroom shelves that are predominantly from the Ronalds collection.

 

 

Book Boxing

Prior to the move out of Savoy Place in 2013, many of the more valuable and fragile rare books, mainly from the S P Thompson collection, were measured. These measurements were used to make ‘book boxes’, which were then fitted to provide further long-term protection to the individual books prior to being them being packed and transferred to archive quality storage (compliant with PD5454:2012). Those boxed books are shown in the image below, now situated on the shelves in the strongroom at Savoy Hill House.

More Unusual Subject Matter in the Rare Books Collection

Given that the SP Thompson collection is commonly called ‘the electrical library of Silvanus P Thompson’, there are perhaps unexpectedly, many books on matters perhaps considered less electrical. One such example is an old work on amber, illustrated below.

 

 

 

The volume called, ‘historiae succinorum corpora aliena involventium et naturae opera pictorum et caelatorum…’, by Nathanael Sendel (1686-1757) is dated 1742. Amongst other things this work describes the formation of amber and its properties and contains a series of plates illustrating animals and plants encased in amber. It has been said that this work laid the foundation for future paleobiological amber research.

A Map Puzzle

Within the S P Thompson rare books collection there is a wonderful ‘map of the arctic regions’, 1597, supposedly by Cornelius Wytfliet which is shown below.

 

 

The map comes with two slips of paper written by Thompson. The first slip says that the map, exhibited by S P Thompson, was a map of the artic regions from 1597 and that it was probably by Cornelius Wytfliet. The second slip says the following;

“this map shows at the North Pole a high black rock. It also shows in the artic sea to the north of Eastern Siberia two positions for the alleged Loadstone Rock or magnetic pole, one located on the hypothesis that the line of no variation passes through Cape Verde, the other on the hypothesis that it passes through the Island of Corvo in the Azores. At an outlet of Davis Strait, north of Labrador, it bears the inscription, a furious over-fall.”

However, other sources would suggest that this map, titled, ‘Septentrionalium Terrarum descriptio, 1597’ is not by Wyfliet but is instead by C Loew (pseudonym for Matthias Quad), after Mercator, published in 1598 from the book "Meer oder Seehanen Buch", Colonia, 1598.

Electrical Association of Women (EAW) Rugby Branch Records

Earlier this year the IET Archives received a donation of papers related to the Rugby Branch of the Electrical Association of Women (EAW). The papers came from the family of Mrs D M Bastow who was Chairman of the Rugby Branch from 1976 until the disbanding of the branch and the EAW in December 1986. Mrs Bastow was also a member of the EAW’s National Executive in the final years of the EAW and some of her personal and National Executive papers and material can be found amongst these branch records.

Some of the papers in the deposit had signs of mould and so the collection was originally quarantined, before being sent for treatment. Once the papers had been cleaned they were then in a position to be catalogued.

EAW Records and the Records of the Rugby Branch

The EAW was formed in 1924 and eventually had several hundred branches in the UK and overseas. The Rugby Branch was founded in 1928 and its inauguration certificate from 25 October 1928, which came with the donation, is shown below.

 

 

The menu and programme from the first annual dinner, held at the Grand Hotel, Rugby, 23 November 1929, shows that members enjoyed the following courses; julien soup; fried sole with an anchovy sauce; roast chicken with ham, boiled and baked potatoes, savoy; apple tart and cream; finished with Welsh rarebit and coffee. The meal was accompanied by toasts, a duet, songs and a pianoforte solo.

 

 

A lengthy report of the annual dinner in the local press, detailing all the participants and details of the speeches and toasts, is very much of its time. The proposer of the ‘visitor’s toast’, Mrs H de B Knight, welcomed the visitors and explained to them that, “while the EAW was a women’s organisation, and therefore independent, they welcomed the mere males who were present, because they provided the wherewithal to purchase the many electrical fittings which the modern woman requires in her home”.

After the EAW was disbanded in 1986, the EAW’s central records were deposited in the IEE Archives (reference NAEST 093 and NAEST 093A) together with a selection of EAW branch records (reference NAEST 093B). However the majority of the many branch records were deposited at local record offices.

The EAW was structured so that the branches were affiliated to an Area Federation. In the case of the Rugby Branch it was a member of the East Midlands Area Federation. The records of 4 East Midlands Area branches, Lincoln, Mansfield and District, Mansfield Evening, and Tamworth and District came to the IEE. However other branch records, including some Rugby Branch records were deposited amongst the Records Offices of Humberside, Leicestershire, Lincolnshire, Northamptonshire, Nottingham and Warwickshire. A list of what records went where is held in the IET Archive Centre. The EAW poster below (NAEST 093/11/16) shows the EAW’s branches in the UK, with the colours representing different Area Federations. The East Midlands Area is shown towards the bottom of the picture in pink.

 

 

EAW Tea Towels – The Discovery of Some New Varieties

One of the nice surprises about this donation is that it contained material produced centrally by the EAW but which has not survived in the central collections and which we had not seen before. For example there were two new, previously unseen, EAW tea towel, one of which is shown below.

 

 

There was also Mrs Bastow’s National Executive member medal which does not exist in the central EAW collections.

 

 

The EAW Rugby Branch papers have now been catalogued (reference NAEST 093B/5/5) and are available to view in the IET Archives. The contents of the collection can be viewed in the IET Archives online catalogue by entering the term ‘UK0108 NAEST 093B/5/5’ in the search engine which can be found here http://archives.theiet.org/search.aspx .

Gustav Wikkenhauser (1901 - 1974) - a Television Pioneer

The IET Archives recently received a donation of papers belonging to Gustav Wikkenhauser, who was described in his obituary as a pioneer of television. 

Gustav was born in Budapest, Hungary, in 1901 and received his degree in mechanical and electrical engineering from the University of Budapest in 1926. He was then employed by AEG in Berlin before joining the laboratories of the Telehor Television Company on its formation in 1929. He worked in Berlin on the early stages of mechanical television and was invited to come to Britain in 1932 to work on television in the UK where he started to work for the company Scophony Ltd. A photograph of Gustav from later in his life is shown below.

 

 

Scophony Limited

Scophony operated internationally in Britain and Germany in the early 1930s and in Britain and America in the late 1930s. It has been described as one of the most highly original television manufacturers of the 1930s and praised for its innovative optical-mechanical television systems which produced large screen high-definition pictures for both the home and cinema. More information about Scophony can be found on the National Media Museum’s blog site here http://blog.nationalmediamuseum.org.uk/2014/03/21/the-last-remaining-scophony-tv-receiver-high-speed-scanner-motor/ . The blog, also mentions Gustav and his involvement with Scophony and mentions that it was Wikkenhauser who built the two 30 line television receivers that Dénes Von Mihály, the Hungarian inventor and engineer, demonstrated at the 1928 Berlin Radio Exhibition.

R W Burns in his book, ‘British Television: The Formative Years’ (IEE Technology Series No.7), commented, “there is no doubt that the Scophony engineers, Walton, Wikkenhauser, Sieger, Robinson, and Lee, produced some of the most highly original devices ever seen in the field of television.” Burns’ book, available via the IET Library, has a chapter on the work of the Television Committee and high definition television in 1934 which also discusses the four competitor companies engaged in research on high definition systems at that time which were; Scophony Ltd; A C Cossor Ltd; Baird Television Ltd; and Electric and Musical Industries Ltd / Marconi-EMI Television Company Limited.

The War Years

Gustav became a naturalized British citizen in 1941 and was awarded the MBE for his scientific work at that time. It was after the war, in 1946, that Gustav married his second wife, Pamela.

Gustav’s work during the war remains something of a mystery although the depositor of the collection believes that there was a connection with radar. There is a series of Gustav’s papers in The National Archives, dating from 1939 to 1946 (reference HO 405/59934) which until only very recently had been closed (records opened to the public 30 October 2014).

Post-war Years

In 1947 Gustav became Chief Development Engineer for Kelvin Hughes (division of Smith Industries Ltd), of Barkingside, where he researched navigational instruments. Despite his work on early television, Gustav’s obituary comments that he was internationally known for his research into scientific instruments. The photograph below shows Gustav alongside Francis Chichester, the aviator and sailor, in front of Kelvin Hughes’ instrumentation in 1962.

 

 

Despite his involvement with navigational instrumentation Gustav retained an interest in television which we know from photographs contained within the deposited papers. There are several photographs taken at the Milan Fair for International Motion Pictures (MIFED) in 1960 where Gustav is photographed as a speaker alongside other pioneers of television such as Vladimir K Zworykin (inventor of a television transmitting and receiving system employing cathode ray tubes) – see below.

 

 

Gustav was made a Freeman of the City of London in 1958 and was a member of many professional organisations over his career. He was a Fellow of The Television Society, a Member of the British Institution of Radio Engineers (one of the predecessor organisations of the IET), a member of the Worshipful Company of Scientific Instrument Makers, and a Fellow of the Institute of Navigation. He retired in 1967 but continued to work as a consultant for Shell International Marine Ltd, for whom he researched the measurement of ship's motion. Gustav died aged 73 in 1974.

Personal Interests

Gustav, in addition to being an exceptional engineer, enjoyed socialising, and was a keen sailor. There are many personal photographs within the deposited collection and two of these, showing a very glamorous Gustav and Pamela, and Gustav sailing his boat off the Isle of Wight are shown below.

 

 

 

 

The Gustav Wikkenhauser papers have now been catalogued (reference SC MSS 257) and are available to view in the IET Archives. The contents of the collection can be viewed in the IET Archives online catalogue.

Allen West - a Key Figure in British Electrical Equipment Manufacturing

The IET Archives recently received the donation of a very large black & white photograph of Allen West, which measures 104cm by 90cm, and which is reproduced below. The name of Allen West will be unfamiliar to many people but he was the founder of the company Allen West & Co. Ltd in 1910 which grew to become one of the UK’s largest manufacturers of control gear and switchgear in the 20th century. The company, which once employed over 3000 people in the UK and had branches and representatives all around the world, no longer exists as Allen West & Co, but following a management buyout in 2007 the rights to the Allen West products and associated records are now held by the company Allenwest Brighton Ltd.

 

 

The story of the Allen West company from 1910-1960 is told in the book, ‘The Allen West Story’ which was published for private circulation by the company in April 1960 – a copy of this volume which was presented to the IEE in 1960 by the company can be found in the IET Library. A cropped version of the donated photograph above appears in the book on page 24.

As well as being an engineer Allen West was also a soldier who fought in the Boer war as well as the two World Wars. On the outbreak of the Boer war, he volunteered as a trooper in the Yeomanry and following rapid promotion was given the command of a squadron which took part in the relief of Mafeking. He was wounded at that time and sent to convalesce in Hove.

Allen West was also associated with the British Electrical and Allied Manufacturers’ Association (BEAMA) and was on its Council for many years. Although he gave up the Managing Directorship of the eponymous company in 1933, he remained on the Board for a further 20 years before retiring. He died in 1957 aged 80.

Allen West & Co Ltd

One of Allen West’s first contracts in 1911 was with the Admiralty providing control gear components and it went on to supply starters for many ships of the Royal Navy from aircraft carriers to midget submarines. The company also supplied many industrial concerns such as steelworks, power stations and mines where it supplied controllers for mine hoists and haulages.

In World War II, the company played a part in the development of radar. It manufactured self-contained radar trailers and equipment for long range detector units. It also supplied special control gear for apparatus used to protect vessels from magnetic mines.

The IET Archives also holds some Allen West & Co material within its other collections for example some of its product leaflets can be found in our Croyden ‘A’ power station collection (reference NAEST 001/1/100) as well as connection diagrams within the same collection (reference NAEST 001/1/132). Leaflets for circuit breakers and switches are illustrated below.

 

 

 

The History of the Allen West Photograph

The Allen West photograph was kindly donated to the IET Archives by the Parmley Graham company. It’s Chairman, Mike Wilson, tells the following story about the photograph;

“My first recollection of seeing this rather imposing photograph was on the grand staircase of the Brighton head office of Allen West & Company, when I arrived there for training in 1966. J Parmley Graham & Sons Ltd, the firm which had just recruited me from ICI Heavy Organics Chemical Division, (now Parmley Graham Ltd) had been appointed as the Allen West Agent in North-East England in the early 1900’s just as Allen West was getting started.

Allen West and James Parmley Graham became friends whilst serving their apprenticeships on Tyneside at J H Holmes and Co., a manufacturer which eventually became Reyrolle then NEI, Rolls Royce and is now Siemens. By 1910 JPG as agent had secured the first order for six large reversing haulage controllers for a colliery in the North-East, which were still working twenty years later. The relationship prospered because of the huge requirement there was for Allen West products, like the newly invented drum controller, for use in the coal steel and chemical industries. The firm’s marine control gear was also in great demand and it is claimed that there was not a single Royal Naval vessel afloat in both world wars which was not extensively equipped with Allen West Gear, in the engine room and on deck.

When I arrived on the scene, there were 3500 employees in Brighton, plus those in its subsidiary companies in Canada, South Africa, Rhodesia and France. However, the notion of selling industrial goods through an agent was already passé, but such was the success of the North-East England Agent, it remained in place when every other area of England and Scotland were made into Allen West regional offices.

During those heady days when our links with Allen West were very strong and we were by far their largest distributor, the directors were moved in 1992, to send to me an appreciative plaque celebrating 82 years of co-operation together with a copy (I think) of the photograph of Mr Allen West which I had so revered at the beginning of my career.”

An Interesting Shareholder!

We are also grateful to Mike Wilson for supplying us with a copy of a handwritten list of the early Allen West & Co shareholders shown below.

 

 

Albert Slazenger, of sports equipment fame, appears on the list with a large holding of 23,000 shares. Mike believes that at some point around the time of this circa 1910 list, Allen West was also involved with the manufacturer of Slazenger’s tennis racquets!

The Allen West photograph has been catalogued as SC MSS 256 and can be viewed by appointment at the IET Archives Centre at Savoy Hill House.

Oliver Heaviside, FRS, (1850-1925) - the Brilliant and Controversial Figure who Still Excites Passions Today

Oliver Heaviside, an important figure in the history of mathematics and electrical engineering, has close connections with the IET. He was the IEE's first Faraday Medal winner in 1922, and the IET Archives holds a significant collection of Heaviside's papers (SC MSS 5). The IET also has an oil portrait of Heaviside painted in 1945 by Francis Hodge. A photograph of Heaviside is shown below.

Oliver Heaviside was born in Camden Town, London on 18 May 1850, the youngest of four sons born to Thomas Heaviside and his wife Rachel West, whose sister Emma had married Sir Charles Wheatstone in 1847. Thomas Heaviside was a wood engraver and his wife was a governess and had taught the Spottiswoode family, including Sir William Spottiswoode who became President of the Royal Society. However, the family were very poor and the poverty of those early years had a lasting influence on Oliver. His education began at a girls' school run by his mother, but when this failed he was taught by Mr F R Cheshire at the Camden House School. He did not go to university but became a telegraph clerk for the Anglo Danish Telegraph Company, later the Great Northern Telegraph Company, in Newcastle upon Tyne in 1868.

In 1874 he retired from work due to increasing deafness. He then began work on a series of problems in telegraphy and signal transmission using experimentation, mathematics and vector analysis. He worked on Maxwell's equations concerning the electromagnetic theory of light. He predicted the existence of an ionised reflective layer in the atmosphere which would bounce radio signals back to earth - the ionosphere - which is known as the Heaviside layer in his honour, and also predicted the existence of sub-atomic particles and the idea that the mass of an electric charge increases with its velocity.

Heaviside was a difficult and eccentric man, caused partly by his deafness, and he cared nothing for the opinions of other scientists. He was convinced of the correctness of his workings using mathematical notation (vector algebra) which was almost impossible to understand by his contemporaries but which forms the basis of important areas of electrical engineering theory to this day. He had long and famous disagreements with Sir William Henry Preece over the introduction of inductance to long distance communication cables to improve the transmission of signals. Heaviside also disagreed with Lord Kelvin over the process by which electricity travelled down wires, leading to the production of Heaviside's transmission line equations, and over Kelvin's use of heat diffusion theory to calculate the age of the earth. However, Kelvin remained a lifelong friend of Heaviside.

Heaviside moved to Paignton in Devon with his parents to live near his brother Charles and his family. Both his parents had died by 1896 and in 1897 Heaviside moved to Newton Abbott where he lived until 1908 when he moved in with his sister in law's sister, Miss Mary Way in Torquay. He lived there until his death on 3 February 1925. In addition to the award of the Faraday Medal by the IEE he was made an Honorary Member of the AIEE. His published works include numerous papers and articles, Electromagnetic Waves (1889), Electrical Papers (1892) and Electromagnetic Theory (3 vols 1893-1912).

Heaviside's Papers in the IET Archives

After Heaviside's death in 1925, his nephew (Frederick Heaviside of Torquay) sold most of the papers he had gathered at his uncle's house to private collectors. Two years later in 1927, he sold the residue to the IEE for £120. This material was examined, soon after its arrival, by IEE member H J Josephs who commented, 'it did not contain any letters written by Heaviside himself; but it did contain letters from friends who were trying to get his fourth and concluding volume of Electromagnetic Theory published in America'.

Then in 1957, three large sacks of papers were found hidden under the floorboards of Heaviside's room in the house at Paignton where he lived from 1889 to 1897. These papers, which have been discussed in subsequent monographs, can also be found within the IET Archives Heaviside papers collection.

In addition to the Heaviside papers collection, Heaviside related material can be found widely throughout the other collections within the IET Archives. For example, there is a series of correspondence dating from 1922-1925 between J S Highfield, IEE President, and Heaviside about the award of the Faraday Medal (SC MSS 68), an audio recording on vinyl dating to 1950 which is a tribute to Oliver Heaviside by Oliver E Buckley, President of Bell Telephone Laboratories (IET/SPE/2/55); and there are numerous letters.

One such letter dated 8 October 1922, reproduced below, is a letter from Heaviside to the Brown family, saying that he had read a copy of the late William Gordon Brown's paper, admiring the quality of the work for one so young, and suggesting, "I do not think the Military Authorities should have accepted him as a fighting soldier. Ruffians are wanted for that. And I think the Military Authorities were very wrong in not overcoming the G.B.'s refusal by the simple process of compulsorily promoting him to one of their numerous scientific departments in which high mathematics would have been more useful than in the trenches'.

Heaviside Biographies and Appreciation of Heaviside

A volume titled 'The Heaviside Centenary Volume' was published by the IEE in 1950, which includes addresses made and papers presented at the Heaviside Centenary Meeting, 18 May 1950. However, there have been several recent biographies published since the 1980's., the latest of which is the 2009 work titled, 'Oliver Heaviside: Maverick Mastermind of Electricity' by B Mahon (volume 36 in the IET's History of Technology Series). These biographies are available in the IET Library.

Heaviside's importance continues to be recognised today and there are many enthusiastic supporters and promoters of his legacy. A current project involving Heaviside is called The Heaviside Memorial Project which aims to fund, through public subscription, and organise the restoration of the memorial to Heaviside and his family found in Paignton Cemetery, near Torquay. Here is a link to the website for that project which shows pictures of the cemetery plot and has a photograph of the Torbay Civic Society's blue plaque commemoration of Heaviside on the building where Heaviside lived between 1889 and 1897

A picture is worth a thousand words
We are all familiar with photographs. They dominate social media such as Facebook, and Pintrest where the audience is invited to comment on what they see. It is an engaging activity, one in which the viewer becomes part of the process, the object the subject too. However, photography and the sharing of images is nothing new. Each photograph taken has had an audience in mind and how we interpret those images can reveal much of society's conventions.

The science behind the image

It is not the purpose of this blog to discuss the inventor of photography as many can lay claim to this accolade. But for simplicity's sake Louis Daguerre developed the daguerreotype process in 1839. The metal-based daguerreotype came in to competition from the paper-based calotype negative invented by Henry Fox Talbot. Fox Talbot made the first surviving photographic negative on paper in Britain in 1835.
Since then photography and the chemical process behind it excited scientists in to perfecting the art. One of those scientists was Sir Joseph Wilson Swan.



Swan was apprenticed to a chemist in his native town of Sunderland. He later became a business partner in a pharmacy in Newcastle which manufactured photographic plates. His interest in photography led him to make significant improvements in the field.

The first practical process for negatives on glass was introduced by F. Scott Archer in 1851. A sheet of glass was coated with a thin film of collodion (guncotton dissolved in ether) containing potassium iodide and was sensitised with silver nitrate. The plate had to be exposed while still wet. Swan and his partner, John Mawson, produced collodion and their improved technique gained recognition.

In addition to the collodion process Swan discovered how to make a sensitive dry plate in place of the less convenient wet collodion process and patented the method of printing using the carbon process in 1864. By 1871 R. L. Maddox proposed the use of silver bromide in gelatine to make dry photographic plates. Swan experimented and perfected the process and by 1877 Mawson and Swan's bromide plates were renowned. In 1879 Swan followed this success with the invention of bromide paper.

Swan is also remembered for his work on the incandescent electric lamp. More information about this can be found on the IET's biography on Joseph Swan. Among his many distinctions he was president of the Institution of Electrical Engineers in 1898.

Other scientists and inventors associated with the development of photography and the IET are Michael Faraday, Sir Francis Ronalds, Sir William Crookes and Silvanus P Thompson.

The collections of Faraday and Ronalds correspondence, deposited with the IET Archives, covers the subjects of early photographic processes. There is also a collection of pamphlets belonging to S P Thompson on the subject of photography.

Some examples of different photographs within the IET Archives

The portrait photograph developed from the painted portrait that has its roots in the Renaissance. Photographs of individuals imitated the conventions of portraiture such as pose, background and accessories. They were commissioned by the sitter and taken by a commercial photographer for a fee. Later as photography became more affordable and practical amateurs began to take photographs as a leisure time activity.

The earliest photograph in the IET Archives is a daguerreotype of Michael Faraday and William Thomas Brande in a presentation case. It was taken in 1848 by Maull and Polybank with a note by S P Thompson explaining that it was given to him by Sir William Crookes on 22 February 1913. The daguerreotype is a highly polished silver surface on a copper plate which was sensitised by iodine fumes exposed in a camera and the image developed by exposure to mercury powder. It can be easily damaged by touching therefore the case served as a means of protection as much as having an aesthetic quality.



An expression of time

As with painted portraits the early photograph was designed to portray the positive virtues of the subject. It is often remarked that Victorian photographs are devoid of emotion and facial expression. However, if one understands the conventions of the time then we can appreciate that they were trying to epitomise the ideal expression and reflect that on to the audience. They wanted to project the notion that they were dignified, pensive, absorbed in thought which in turn is what they wanted the viewer to emulate.

Similarly the pose was also important. Standing or seated can mean authority or an ease with his surroundings. Props and backgrounds can tell us a lot about the subject too. This harks back to painted backdrops used to create a stage. Books and scientific apparatus signify education, literacy and expertise in their chosen field.



A sense of touch

The Victorians believed that intimate emotions such as those conveyed through touch were not appropriate on display in publically viewed photographs. Therefore many family portraits or those of husbands and wives will show them distanced from each other or any physical contact is lacking in affection. Yet two photographs in the IET Archives collection show otherwise.

Michael Faraday married Sarah Barnard on 12 June 1821. There is little evidence to suggest as to the congeniality of their marriage but Faraday's collection of correspondence often refers to his wife and this photograph shows warmth between the two. It is interesting to note the direction of their gaze as this did comply with common practice. Faraday looks straight ahead which projected a sense of strength and engagement. Women on the other hand usually averted their gaze to suggest modesty.



Another photograph of F H Webb, Secretary of the Society of Telegraph Engineers, taken c1890 shows a pose with a child. Nothing is known about this photograph but it can be surmised that the child has a close relationship with Webb given the visibly affectionate composition.



This is just a snapshot of the many different types and subjects of photographs we hold in the IET Archives. For more information please see our online catalogue.

If this has sparked an interest in photography why not check out the Newcastle Photography Festival "A celebration of photography inspired by Joseph Swan and his adventures with carbon, collodion and light". It runs from 20-26 October 2014 and more information can be found by visiting: http://newphotofest.com

The Young Trophy and the Beginning of a Young Photographer's 60-Year Relationship with the IEE!

The Young Trophy is a prize awarded in a sporting competition between the student and graduate sections of professional engineering institutions. The competition first took place in 1933 when the student and graduates sections of the Institution of Civil Engineers and Institution of Mechanical Engineers jointly challenged the Institution of Electrical Engineers to compete in cricket and tennis matches.

Henry Thomas Young, Vice President of the IEE at the time and who went on to become President in 1936, was so impressed by the sporting spirit displayed on this occasion that he presented a trophy to be competed for annually by all three Institutions. This trophy was called the ‘Young Trophy’ in his honour.

Within a few years the sporting competition included additional sports not just cricket and tennis. The Young Trophy continues to be awarded to this day but now embraces teams comprised of students and young professional from a wider range of engineering institutions. In 2014 the format was a 5-aside football tournament and on 5 July 2014 the Institution of Civil Engineers were crowned champions with teams from the Institute of Acoustics and the Institution of Mechanical Engineers in 2nd and 3rd places respectively.

The Origins of the Trophy

The 30th anniversary programme, held in the IET Archives, explains how the first challenge and subsequent tournament began in the summer of 1933 when a challenge was sent to the Students’ Section of the IEE stating:

“The Chairman and Committees of the London Students of Civil Engineering and the Graduates’ Section of the Institution of Mechanical Engineers SUMMON HEREBY the Chairman and Committee of the Students’ Section of the Institution of Electrical Engineers to show their worth and prove their skill at the noble game of CRICKET and other manly sports, failing which shall they be declared poltroons and knaves in the sight of all Sportsmen.”

The reply, delivered in the same tone of humour, said:

“To all Apprenticed Enginewrights and Claypuddlers, know ye that whereas your betters in Council assembled, to wit the Chairman and Committee of the most exalted Institution of Electrical Engineers, have deigned to consider the presumptuous and overweening screed delivered these few days gone by a consortium of rude Mechanicals and indignant Civils (not excluding the Sanitary Branch), and have seen fit of their special grace and mere motion to treat with those arrogant and effete survivals of a murky and uncertain origin. Know ye also, o men of little worth, that ye enter upon this enterprise at your several perils, there being a very present risk of your being smitten hip and thigh by our superior prowess. Take heed, therefore, lest our most puissant might be loosed in tourney against ye. In fine- take heed!”

Following this verbal jousting, battle commenced on 1st July 1933 at Boston Manor and both cricket and tennis were played. The event was attended by Sir Murdoch MacDonald, ICE President; L. St. L. Pendred, Past-President of the IMechE, and Henry Thomas Young, Vice President of the IEE. The report of the event was as follows;

“The cricket began at a fast pace with the IEE batting first with a score of 120 for 8. However, the claypuddlers were on fighting form clocking up 40 runs before the IEE captain broke-up this dangerous partnership in his first over. The challenger's innings closed for 89. The tennis had the difficulty of a shortage of players as they were all in the cricket match! This did not dampen spirits and six doubles were played in all of which the IEE were victorious.”

In the early years it was agreed that the meeting should be a three cornered one. The holder of the Trophy, being challenged by one of the other Institutions, and the winner decided in a knock-out competition. The Electricals followed their success of 1933 by winning the Trophy in 1934. In 1937 the Young Trophy was won for the first time by the Institution of Civil Engineers.

1937 Young Trophy Competition and a Photographer at the Start of his Career as an Engineer

The IET Archives has very recently received a donation of two photographs, taken at the 1937 Young Trophy competition, which can be seen below (catalogued as IET/UNO/2/4). The photographs were taken by Norman R Rice, a Student member of the IEE and also a member of the IEE’s London Student’s Section. The photographs were donated by Norman's son Peter J Rice.

The first photograph shows the Young Trophy being received for the first time in its history by the Institution of Civil Engineers with Mrs H T Young, who presented the trophy, in the background..

 

A report about the 1937 competition, which at that time comprise shooting, tennis and cricket, was printed in the IEE’s Student’s Quarterly Journal under the title ‘Young Trophy changes hands: Civil persistence triumphs’. An extract from the report says;

“Last year the Civils swore by all their gods that they would wrest the Young Trophy from us this year. Their ju-ju appears potent, for they succeeded by a handsome margin. As explained elsewhere, we were a poor second in the shooting tie, scoring only 80 as against 121. Our tennis was certainly on a higher level, but even so we again lost to the Civils by 5-4. This can only be attributed to those members who promised to play and then two days before the matches asked to be excused…. The cricket was much more successful, although here again our team was short of one man. However, we managed to give the Civils a run for their money, and were only beaten by 7 runs.” A full cricket scorecard is also given in the report.

The second photograph shows spectator’s at the Young Trophy including Henry Thomas Young himself (second person on the left).

 

The photographer for these two photographs, Norman Richard Rice, joined the IEE as a Student member in 1931 and he studied electrical engineering at Battersea Polytechnic from 1931 to 1934. Norman graduated with a BSc (Eng.) in 1934 and became a Graduate member of the IEE. His link with the Young Trophy and the London Student’s Section can be explained because in 1933 (aged 20) he was Assistant Secretary for Visits, IEE London Students Section and he became Vice Chairman of the London Students' Section in 1935.

Little could Norman have envisaged at that time that he would retain his link to the IEE for over 60 years! Having joined in 1931, he went on to became an Associate Member in 1940 and a Member in 1966, when the membership category structure changed. His name continued to appear on the IEE’s published membership lists until his last appearance on the list of 1994/1995.).

IEE Pre-1930 Membership Records Now Available on Ancestry - Uncovering the Hidden Engineers including Jekyll and Hyde!

The pre-1930 membership records held by the IET Archives consist of the IEE’s membership application forms pre-1902 (no physical application forms exist after 1902) and also the published membership lists of the IEE. In 2013 Ancestry, the company which provides online resources to family historians, began a programme to digitise these records. Those records recently became publicly accessible via Ancestry’s website.

All visitors to the IET Archives, IET Library and Michael Faraday House, Stevenage can access the full Ancestry.com website, not just the IEE’s membership records, for free from selected computer terminals at those locations. In addition IET Members worldwide can access IEE records on Ancestry, by contacting the IET Archives with their membership number, and we will provide details on how to log in. Further information on these digitised records and how to access them can be found on the IET Archives website page with the web address, http://www.theiet.org/resources/library/archives/family-history/ancestry-index.cfm

The digitised pre-1930 records can be used to find the membership application forms of engineers who joined either the Society of Telegraph Engineers (STE), since its creation in 1871, or who joined its successor, the Society of Telegraph Engineers and Electricians, which then became the Institution of Electrical Engineers in 1889. Amongst the membership application forms can be found those of many noted engineers for example, Nikola Tesla. The 1891 application form for Nikola Tesla to join the IEE as a Foreign Member is reproduced below.

 

 

Jekyll and Hyde and their links to the Institution of Electrical Engineers

The link between the published membership lists and Jekyll and Hyde is a story that was told by Sarah Hale in the ‘from the vaults’ column in the IET’s Member News, March 2013. The story is repeated below;

“Most people will be familiar with the 1886 novella ‘The Strange Case of Dr Jekyll and Mr Hyde’ by Robert Louis Stevenson, the tale of a morally just man who transforms into an evil criminal after consuming a self-invented potion. The phrase ‘Jekyll and Hyde’ has since become a by-word to describe anybody or anything with a split personality, but where did Stevenson find inspiration for these intriguing and somewhat unusual names? As a novelist with a vivid imagination, it may be that he simply plucked them out of thin air, indeed, the name Jekyll originates from Stevenson’s native Scotland; but there is some evidence to suggest that he took these names from the first membership list of the Society of Telegraph Engineers.

The link between Jekyll and Hyde and the STE was first noticed by Rollo Appleyard in his book ‘The History of the Institution of Electrical Engineers 1871-1931’. When discussing the early days of the STE and referring to the membership list, which was published in 1872, Appleyard noted “the curious addition of Jekyll and Hyde”. ‘Jekyll’ was Lt H Jekyll, Royal Engineer, and one of the first members to join in 1871, while ‘Hyde’ was Major General H Hyde of the India Office, another prominent telegraph engineer of the time. There is also another name in the list that corresponds with a character in the novella, Frederick C Danvers, who shares a name with Hyde’s victim in the book, Sir Danvers Carew. A number of other characters also share names with civil and mechanical engineers of the 18th and 19th centuries, such as Inspector Newcomen, who possibly derived his name from the famed steam engine inventor.

Coincidence?

These links were passed off as coincidental and not pursued further until 1949, when the IEE contacted the Society of Genealogists to ask them to research into the possibility of a relationship between Stevenson and Edward Alfred Stevenson, a member of the STE who also appears in the first membership list. The IET Archives hold a copy of the report that the Society of Genealogists sent to the IEE as a result of this research. It was concluded in the report that there was no link between Robert Louis Stevenson and Edward Alfred Stevenson, and suggested that Robert Louis Stevenson may have found access to the STE membership lists via his father, who was a prominent Scottish lighthouse engineer. There may have been some truth in this, but it is also possible that Stevenson came across the membership lists another way. As well as being the son of a lighthouse engineer, Stevenson studied engineering at the University of Edinburgh. Though he would come to loathe the subject and seek a career as a writer, Stevenson developed a close friendship with his professor at Edinburgh, Fleeming Jenkin. While Jenkin was a pioneering electrical and telegraph engineer, both men shared an avid interest in poetry and theatre and took part in amateur dramatics together. When Jenkin died suddenly in 1885 Stevenson was distressed and shocked. To aid the grieving process he began writing a memoir of Jenkin that was completed in 1887.

Friendship

It is Stevenson’s friendship with Jenkin that perhaps provides the strongest evidence that he was inspired by the STE membership list for his characters’ names in ‘Jekyll and Hyde’. He wrote the book at the same time as writing Jenkin’s memoir during a period of intense activity and so it is likely that his research for the memoirs may have influenced the thinking behind the novella. This idea is compounded when one actually looks at the page of the STE membership list that contains the names of ‘Jekyll and Hyde’. Col H Hyde and Lt H Jekyll are right next to each other, while Fleeming Jenkin FRS MICE, of 5 Fettes Row, Edinburgh, is two places directly below Jekyll. Did Stevenson look up Jenkin’s entry in the STE membership lists, and see the names of Jekyll and Hyde so close together and be inspired, consciously or subconsciously, to use them in his latest work of fiction?”

The first published membership list of the STE to which the above story refers is not one of the lists digitised by Ancestry as the list was published as part of the STE journal, but the entry as published in that journal is reproduced below.

18th Century Italian Earthquake Records - Conservation of Rare Books Held in the IET Archives

Whilst the large majority of published books and volumes, regardless of age, are held by the IET Library, there are a small number of rare books which because of their value or fragility are held within the IET Archives.

One such volume is the ‘Carta Corografica Della Calabria Ultiore’, a volume of large maps and engravings which was published in the 1780’s and which illustrates the aftermath of the Calabrian earthquakes of 1783. The 1783 Calabrian earthquakes were a sequence of five strong earthquakes, two of which produced significant tsunamis, which hit the region of Calabria in southern Italy which at the time was part of the Kingdom of Naples. The earthquakes occurred over a period of almost two months, all with magnitudes of 5.9 or greater and which have been estimated to have cause the deaths of 32,000 to 50,000 people.

 

 

The Neapolitan Royal Academy sent an expedition to Calabria following the earthquakes which in addition to causing vast numbers of deaths, destroyed hundreds of villages, caused mountains to collapse, and changed the courses of rivers. Even the coastline was altered as a result of the earthquakes.

The expedition comprised a group of scientists including Michele Sarconi, Angiolo Fasano, Nicolo Pacifico, Padre Eliseo della Concezione and Antonio Minasi as well as architects and draughtsmen. Padre Eliseo was the individual responsible for designing the Carta Corografica, a very accurate overview of the changes experienced by the region.

 

 

One importance of this work by Padre Eliseo is that it is the first seismic map produced in Italy and it rectifies the errors in latitude and longitude in previous maps of the region. Pere Eliseo designed the maps with the help of a ‘macchina equatoriale’ which he himself had invented and which is illustrated on the last page.

 

 

In addition to the numerous plates showing views of the area there are several engravings illustrating fossils such as the following illustration of ‘echiniti’ found near Orsigliadi.

 

 

This volume had been in quite poor condition, with a significant amount of dirt, some water damage and some missing pieces of paper around the edges (not affecting the individual plates). A few years ago the decision was taken that the volume required conservation work to stop any further significant and/or rapid deterioration in the volume. A specialist paper conservator was used to clean the individual pages, and repair the edges of the plates including the filling of the holes with a specialist conservation grade paper.

The restored volume, following conservation treatment, is now wrapped in protective paper within its own ‘book box’ and is stored in the Archive Centre strongroom and through this intervention is available to be consulted by both researchers and members of the IET.

Historical records such as these can often be used by present day researchers to re-evaluate past events and develop a better understanding of seismic activity. In the case of the Calabrian earthquakes there was a paper published in 2006 in the journal Natural Hazards and Earth System Sciences titled, ‘A revision of the 1783-84 Calabrian (southern Italy) tsunamis’, which analysed historical sources to calculate that there had been 3 more tsunamis than previously estimated, and that the tsunamis had been previously underestimated and ‘erroneously considered a minor event’.

New Collections Recently Deposited with the IET Archives

The IET Archives continues to receive a steady stream of fascinating deposits related to the history of engineering and technology and to key individuals who made important contributions to those sectors. Two such recent deposits are highlighted below.

Records of the STC Technical Society, latterly The Technical Society

 

The recent deposit comprises papers of the Society, primarily from the 1980’s and early 1990’s, and includes items such as committee minutes, details of programmes and events, and accounts.

The Society was founded as the Western Electric Engineering Society in 1912, a technical society for employees of Western Electric, which held regular technical meetings, lectures and organised visits. Western Electric began life in London as International Western Electric in 1883 (an agent for the US company Western Electric). The original notice proposing the Engineering Society was circulated amongst members of the Engineering Department on 5 September 1912.

In 1925 Western Electric's international operations were bought by ITT Corporation of the US and the company's UK operations were renamed Standard Telephones and Cables.

Soon after the end of World War II the Engineering Society was continued as the STC Telephone Technical Society (TTS). Members were then mostly electro-mechanical engineers and sales engineers with other members of the Telephone Division. Personnel engaged in, and associated with, the Manufacturing Division (Telephones) were allowed to become Associate Members subject to Committee approval. The highest number of members was just under 600 and in May 1985 membership totalled 551.

The 12 May 1989 constitution of the STC Telephone Technical Society (issue 14) shows that Full Membership was open to all employees of STC plc. Associate Membership was open to previous employees of STC plc who had retired and had been approved by the Committee. A class of Honorary Members could be elected by the Committee and there was an Associates class for people connected with Full Members.

In 1991 STC was bought by Northern Telecom of Canada (Nortel) and the name of the Society was changed to The Technical Society still referred to as TTS.

The collection has been catalogued as NAEST 227 and forms a useful addition to the collection of papers of STC, including photographs, related to its site at New Southgate (collection NAEST 211). NAEST 211 is a very large collection and is currently being catalogued as part of a long term project. The photograph below is one of the many images held within numerous albums in NAEST 211

 

 

Paul Voigt papers 

Another recent addition to the IET Archives is a collection of photographs related to Paul Voigt (collection SC MSS 111/3) which joins a small collection of Voigt papers already held in the IET Archives (SC MSS 111/1-2). 

Paul Voigt was born in London on 9 December 1901 and gained a Bachelor of Science degree in Engineering from UCL at the age of 21. Voigt was first employed by J E Hough Ltd in 1922 at the Edison-Bell works in Peckham, London where he was employed for his specialist wireless knowledge. 

By 1926 Voigt had developed the 1st British electric recording system. Many Edison Bell products were protected by patents taken out by Voigt. After the cessation of trading of Edison Bell in 1933 Voigt set up his own company called Voigt Patents Ltd, based in Sydenham, London, and the company's 'Domestic Corner Horn' was released in 1934. 

During World War II the company's main work came from maintaining its horn speakers installed in cinemas. Voigt moved to Canada with his wife in April 1950, having previously come to an agreement with the Lowther Manufacturing Company to produce the Domestic Corner Horn under licence. 

Paul Voigt died 9 February 1981. [biographical information extracted from Lowther Voigt Museum website]. 

The collection was generously deposited by Mr E H Stubbes, a long-term supporter of the legacy of Paul Voigt and one of the main contributors to the ‘pink fish media’ website which is dedicated to promoting the legacy of Paul Voigt. For anyone interested in finding our more about Paul Voigt here is a link to that website; 

http://www.pinkfishmedia.net/forum/showthread.php?s=085231614b4d40c21d017d4685fce1c1&t=78278.

There is very little material relating to Voigt known to survive and the most important photograph within the deposit is the photograph reproduced below which is a photograph of Voigt from the early 1920’s.
