  • 4 Wilkes, Maurice Vincent

    [br]
    b. 26 June 1913 Stourbridge, Worcestershire, England
    [br]
    English physicist who was jointly responsible for the construction of the EDS AC computer.
    [br]
    Educated at King Edward VI Grammar School, Stourbridge, where he began to make radio sets and read Wireless World, Wilkes went to St John's College, Cambridge, in 1931, graduating as a Wrangler in the Mathematical Tripos in 1934. He then carried out research at the Cavendish Laboratory, becoming a demonstrator in 1937. During the Second World War he worked on radar, differential analysers and operational research at the Bawdsey Research Station and other air-defence establishments. In 1945 he returned to Cambridge as a lecturer and as Acting Director of the Mathematical (later Computer) Laboratory, serving as Director from 1946 to 1970.
    During the late 1940s, following visits to the USA for computer courses and to see the ENIAC computer, with the collaboration of colleagues he constructed the Cambridge University digital computer EDSAC (for Electronic Delay Storage Automatic Computer), using ultrasonic delay lines for data storage. In the mid-1950s a second machine, EDSAC2, was constructed using a magnetic-core memory. In 1965 he became Professor of Computer Technology. After retirement he worked for the Digital Electronic Corporation (DEC) from 1981 to 1986, serving also as Adjunct Professor of Computer Science and Electrical Engineering at the Massachusetts Institute of Technology from 1981 to 1985. In 1990 he became a research strategy consultant to the Olivetti Research Directorate.

  • 5 Tizard, Sir Henry Thoms

    SUBJECT AREA: Weapons and armour
    [br]
    b. 23 August 1885 Gillingham, Kent, England
    d. 9 October 1959 Fareham, Hampshire, England
    [br]
    English scientist and administrator who made many contributions to military technology.
    [br]
    Educated at Westminster College, in 1904 Tizard went to Magdalen College, Oxford, gaining Firsts in mathematics and chemistry. After a period of time in Berlin with Nernst, he joined the Royal Institution in 1909 to study the colour changes of indicators. From 1911 until 1914 he was a tutorial Fellow of Oriel College, Oxford, but with the outbreak of the First World War he joined first the Royal Garrison Artillery, then, in 1915, the newly formed Royal Flying Corps, to work on the development of bomb-sights. Successively in charge of testing aircraft, a lieutenant-colonel in the Ministry of Munitions and Assistant Controller of Research and Experiments for the Royal Air Force, he returned to Oxford in 1919 and the following year became Reader in Chemical Thermodynamics; at this stage he developed the use of toluene as an air-craft-fuel additive.
    In 1922 he was appointed an assistant secretary at the government Department of Industrial and Scientific Research, becoming Principal Assistant Secretary in 1922 and its Permanent Director in 1927; during this time he was also a member of the Aeronautical Research Committee, being Chairman of the latter in 1933–43. From 1929 to 1942 he was Rector of Imperial College. In 1932 he was also appointed Chairman of a committee set up to investigate possible national air-defence systems, and it was largely due to his efforts that the radar proposals of Watson-Watt were taken up and an effective system made operational before the outbreak of the Second World War. He was also involved in various other government activities aimed at applying technology to the war effort, including the dam-buster and atomic bombs.
    President of Magdalen College in 1942–7, he then returned again to Whitehall, serving as Chairman of the Advisory Council on Scientific Policy and of the Defence Research Policy Committee. Finally, in 1952, he became Pro-Chan-cellor of Southampton University.

  • 7 Watson-Watt, Sir Robert Alexander

    [br]
    b. 13 April 1892 Brechin, Angus, Scotland
    d. 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.
