Arnold Frederic Wilkins O.B.E., (born 20 February 1907 in Chorlton, Cheshire; died 5 August 1985) was a pioneer in developing the use of radar. It was his offhand suggestion that radio might be used to detect aircraft that led to initial steps to develop radar in the UK, and his lashed-up system used in the Daventry Experiment that successfully detected an aircraft for the first time.

Early life[edit]

He was the son of John Knowles Wilkins of Chester and was educated at Chester City & County School, Manchester University and St. John's College, Cambridge.[1]

He was usually known as 'Skip' Wilkins and worked at the Radio Research Station with Robert Watson-Watt. In an experiment on 26 February 1935 in a field in Northamptonshire at Stowe Nine Churches, Watson-Watt and Wilkins became the first to prove the possibility of radar. Known as the Daventry Experiment, this demonstration detected a Royal Air Force Heyford bomber aircraft at a distance of eight miles. In mid-May 1935, Wilkins left the Radio Research Station with a small party, including Edward George Bowen, to start further research at Orford Ness, an isolated peninsula on the coast of the North Sea. By June they were detecting aircraft at 27 km, which was enough for scientists and engineers to stop all work on competing sound-based detection systems. The successful results of the initial test led to the setting up of a research station that was to become the Telecommunications Research Establishment (TRE).

By the end of the year the range was up to 100 km, at which point plans were made in December to set up five stations covering the approaches to London by Watson-Watt and Sir Henry Tizard. Those stations opened in 1938 with the help of Wilkins and were further extended to the Chain Home system. In 1938, he helped to develop the British version of the Identification friend or foe (IFF) system.

After the war, he worked at the Radio Research Station in Buckinghamshire. His memoirs were written in 1976 and lodged in Churchill College Library, Cambridge.

He appeared in the 1977 TV Series The Secret War explaining his role in the discovery of radar, and is seen to reconduct the original Daventry Experiment alongside TV presenter William Woollard.

Personal life[edit]

He died in Saxtead, near Framlingham, Suffolk. His widow, Nancy, died in Framlingham in 2011. They are survived by three daughters.
