The collection consists of material collected by Fahie in connection with his research mainly on the pioneers of inventions such as the electric telegraph, the wireless telegraph and the electric light. In doing so he brought to prominence names which would otherwise have been unknown despite their important contributions to science, including Edward Davy, Henry Staite, William Petrie and D E Hughes.
Fahie also did considerable work on Galileo. There are also letters to people who worked in early telegraphy, pamphlets and newspaper cuttings about the Atlantic Telegraph and the telegraphs to India. His own articles and letters are included along with the papers of Edward Davy which he published and a manuscript for 'A History of Electric Telegraphy from the Earliest Times to 1837'.
This collection of papers show Davy's first ideas for an electric telegraph from his early sketches in 1836 of a frictional electric telegraph to one worked by electromagnetism which he developed between 1836-1839. The papers indicate his efforts to find a purchaser for the patent rights and to establish a company to develop the telegraph.
The papers record the efforts of his father, Thomas Davy, and several others, to continue Davy's negotiations with railway companies and the arrangements which were made to re-exhibit a working model of the telegraph. The papers also relate to the sale of the patent to the Electric Telegraph Company in 1847. Fahie's memoir on Davy is included in the papers.
