3 Watson-Watt, Sir Robert Alexander
[br]b. 13 April 1892 Brechin, Angus, Scotlandd. 6 December 1973 Inverness, Scotland[br]Scottish engineer and scientific adviser known for his work on radar.[br]Following education at Brechin High School, Watson-Watt entered University College, Dundee (then a part of the University of St Andrews), obtaining a BSc in engineering in 1912. From 1912 until 1921 he was Assistant to the Professor of Natural Philosophy at St Andrews, but during the First World War he also held various posts in the Meteorological Office. During. this time, in 1916 he proposed the use of cathode ray oscillographs for radio-direction-finding displays. He joined the newly formed Radio Research Station at Slough when it was opened in 1924, and 3 years later, when it amalgamated with the Radio Section of the National Physical Laboratory, he became Superintendent at Slough. At this time he proposed the name "ionosphere" for the ionized layer in the upper atmosphere. With E.V. Appleton and J.F.Herd he developed the "squegger" hard-valve transformer-coupled timebase and with the latter devised a direction-finding radio-goniometer.In 1933 he was asked to investigate possible aircraft counter-measures. He soon showed that it was impossible to make the wished-for radio "death-ray", but had the idea of using the detection of reflected radio-waves as a means of monitoring the approach of enemy aircraft. With six assistants he developed this idea and constructed an experimental system of radar (RAdio Detection And Ranging) in which arrays of aerials were used to detect the reflected signals and deduce the bearing and height. To realize a practical system, in September 1936 he was appointed Director of the Bawdsey Research Station near Felixstowe and carried out operational studies of radar. The result was that within two years the East Coast of the British Isles was equipped with a network of radar transmitters and receivers working in the 7–14 metre band—the so-called "chain-home" system—which did so much to assist the efficient deployment of RAF Fighter Command against German bombing raids on Britain in the early years of the Second World War.In 1938 he moved to the Air Ministry as Director of Communications Development, becoming Scientific Adviser to the Air Ministry and Ministry of Aircraft Production in 1940, then Deputy Chairman of the War Cabinet Radio Board in 1943. After the war he set up Sir Robert Watson-Watt \& Partners, an industrial consultant firm. He then spent some years in relative retirement in Canada, but returned to Scotland before his death.[br]Principal Honours and DistinctionsKnighted 1942. CBE 1941. FRS 1941. US Medal of Merit 1946.

4 Tupolev, Andrei Nikolayevich
[br]b. 10 November 1888 Pastomazovo, Russiad. 23 December 1972 Moscow, Russia[br]Russian aircraft designer.[br]In 1909 he entered the Moscow Higher Technical School and became a pupil of Nikolai Zhukovsky, who was known as "the father of Russian aviation". Graduating in 1918, he helped Zhukovsky to set up the Zhukovsky Central Aerohydrodynamic Institute and was made Assistant Director. He was appointed Head of the Institute's Design Department in 1922: his work was concentrated on wind tunnels and gliders, but later included aerodynamic calculations and the construction of all-metal aircraft. His first significant design project was the twin-engined Ant-29 fighter prototype, which appeared in the early 1930s and eventually entered service as the SB-2. However, Tupolev and his wife fell victim to Stalin's purges in 1937: she was sent to a labour camp and he was imprisoned, but in 1943 both were rehabilitated and Tupolev was able to resume his design work. He devoted his attention to long-range strategic bombers, the first of these being the Tu-4, a copy of the US B-29, followed by the Tu-70 bomber. He also designed the Tu-104 airliner, and in 1967 he produced the world's first supersonic airliner, the Tu-144. Tupolev also became interested in fast-attack naval craft and designed a number of torpedo launches, and he rose to the rank of Lieutenant-General in the Soviet air force's Engineering and Technical Service.[br]Principal Honours and DistinctionsHonoured Scientist and Technologist RSFSR 1933. Hero of Socialist Labour 1945. Member of the Supreme Soviet 1950–58. Member of the Soviet Academy of Sciences 1953. Lenin Prize 1957.
