7 Boot, Henry Albert Howard
[br]b. 29 July 1917 Birmingham, Englandd. 8 February 1983 Cambridge, England[br]English physicist who, with John Randall, invented the cavity magnetron used in radar systems.[br]After secondary education at King Edward School, Birmingham, Boot studied physics at Birmingham University, obtaining his BSc in 1938 and PhD in 1941. With the outbreak of the Second World War, he became involved with Randall and others in the development of a source of microwave power suitable for use in radar transmitters. Following unsuccessful attempts to use klystrons, they turned to investigation of the magnetron, and by adding cavity resonators they obtained useful power on 21 February 1940 at a wavelength of 9.8 cm. By May a cavity magnetron radar system had been constructed at TRE, Swanage, and in September submarine periscopes were detected at a range of 7 miles (11 km).In 1943 the physics department at Birmingham resumed its research in atomic physics and Boot moved to BTH at Rugby to continue development of magnetrons, but in 1945 he returned to Birmingham as Nuffield Research Fellow and helped construct the cyclotron there. Three years later he took up a post as a Principal Scientific Officer (PSO) at the Services Electronic Research Laboratories at Baldock, Hertfordshire, becoming a Senior PSO in 1954. He remained there until his retirement in 1977, variously carrying out research on microwaves, magnetrons, plasma physics and lasers.[br]Principal Honours and DistinctionsRoyal Society of Arts Thomas Gray Memorial Prize 1943.

8 Randall, Sir John Turton
SUBJECT AREA: Medical technology[br]b. 23 March 1905 Newton-le-Willows, Lancashire, Englandd. 16 June 1984 Edinburgh, Scotland[br]English physicist and biophysicist, primarily known for the development, with Boot of the cavity magnetron.[br]Following secondary education at Ashton-inMakerfield Grammar School, Randall entered Manchester University to read physics, gaining a first class BSc in 1925 and his MSc in 1926. From 1926 to 1937 he was a research physicist at the General Electric Company (GEC) laboratories, where he worked on luminescent powders, following which he became Warren Research Fellow of the Royal Society at Birmingham University, studying electronic processes in luminescent solids. With the outbreak of the Second World War he became an honorary member of the university staff and transferred to a group working on the development of centrimetric radar. With Boot he was responsible for the development of the cavity magnetron, which had a major impact on the development of radar.When Birmingham resumed its atomic research programme in 1943, Randall became a temporary lecturer at the Cavendish Laboratory in Cambridge. The following year he was appointed Professor of Natural Philosophy at the University of St Andrews, but in 1946 he moved again to the Wheatstone Chair of Physics at King's College, London. There his developing interest in biophysical research led to the setting up of a multi-disciplinary group in 1951 to study connective tissues and other biological components, and in 1950– 5 he was joint Editor of Progress in Biophysics. From 1961 until his retirement in 1970 he was Professor of Biophysics at King's College and for most of that time he was also Chairman of the School of Biological Sciences. In addition, for many years he was honorary Director of the Medical Research Council Biophysics Research Unit.After he retired he returned to Edinburgh and continued to study biological problems in the university zoology laboratory.[br]Principal Honours and DistinctionsKnighted 1962.
