Tizard, Sir Henry
Tizard, Sir Henry (1885–1959),British chemist and scientific administrator who, after serving as a pilot during the First World War, was chosen to head the air ministry's committee for the Scientific Survey of Air Defence (later of Air Warfare) in November 1934. The Tizard committee, as it came to be called, first met in January 1935 and subsequently oversaw the development of Watson-Watt's radio echo system. This became the radar air defence system which helped win the battle of Britain and Tizard was also responsible for encouraging the development of airborne radar (see electronic navigation systems), a possibility he had first suggested in 1936. In June 1940, after expressing his scepticism about the existence of the German Knickebein beam, he resigned as chief scientific adviser to the air staff. Antipathy between him and Churchill's scientific adviser Lindemann, led to his talents being underused for the rest of the war, but in September 1940 he led what became known as the Tizard mission to the USA to explain British scientific advances in radar (most notably the cavity magnetron) and ASDIC, as well as new developments such as the RDX explosives and the proximity fuze. This information enabled much valuable war matériel to be produced in the USA and established Anglo-American scientific co-operation during the war years which culminated in the development of the atomic bomb. He was knighted in 1937. See also scientists at war.

Sir Henry Thomas Tizard
Sir Henry Thomas Tizard 1885-1959, English physical chemist and scientific adviser. He was educated at Westminster school and Magdalen College, Oxford, from which he received honors in natural science in 1908. During the years from the late 1920s to 1942, Tizard became an outstanding authority on aeronautics and championed the development of radar. His 1940 mission to Washington gave impetus to cooperation between scientists and the military in the United States. His own research concerned chemical indicators and aerodynamics, and his work on aircraft fuels led to the common use of octane ratings. |
