Radar (Radio Detection and Ranging) was first developed in Britain in the 1930s. This online exhibition looks at the scientists and engineers behind the development of radar during World War Two.
The first primitive radar system was patented in 1904 by a German engineer, Christian Hulsmeyer. His system was based on principles first discovered by Michael Faraday, and the mathematical work of James Clerk Maxwell who predicted the existence of radio waves and formulated the electromagnetic theory of light.
In 1886 Heinrich Hertz tested Maxwell's theories in a series of experiments which proved the existence of radio waves. By the 1930s scientists in several countries began to tackle the problem of developing what were later called radar systems.
