1 Dassault (Bloch), Marcel
SUBJECT AREA: Aerospace[br]b. 22 January 1892 Paris, Franced. 18 April 1986 Paris, France[br]French aircraft designer and manufacturer, best known for his jet fighters the Mystère and Mirage.[br]During the First World War, Marcel Bloch (he later changed his name to Dassault) worked on French military aircraft and developed a very successful propeller. With his associate, Henri Potez, he set up a company to produce their Eclair wooden propeller in a furniture workshop in Paris. In 1917 they produced a two-seater aircraft which was ordered but then cancelled when the war ended. Potez continued to built aircraft under his own name, but Bloch turned to property speculation, at which he was very successful. In 1930 Bloch returned to the aviation business with an unsuccessful bomber followed by several moderately effective airliners, including the Bloch 220 of 1935, which was similar to the DC-3. He was involved in the design of a four-engined airliner, the SNCASE Languedoc, which flew in September 1939. During the Second World War, Bloch and his brothers became important figures in the French Resistance Movement. Marcel Bloch was eventually captured but survived; however, one of his brothers was executed, and after the war Bloch changed his name to Dassault, which had been his brother's code name in the Resistance. During the 1950s, Avions Marcel Dassault rapidly grew to become Europe's foremost producer of jet fighters. The Ouragon was followed by the Mystère, Etendard and then the outstanding Mirage series. The basic delta-winged Mirage III, with a speed of Mach 2, was soon serving in twenty countries around the world. From this evolved a variable geometry version, a vertical-take-off aircraft, an enlarged light bomber capable of carrying a nuclear bomb, and a swept-wing version for the 1970s. Dassault also produced a successful series of jet airliners starting with the Fan Jet Falcon of 1963. When the Dassault and Breguet companies merged in 1971, Marcel Dassault was still a force to be reckoned with.[br]Principal Honours and DistinctionsGuggenheim Medal.

2 Wallis, Sir Barnes Neville
[br]b. 26 September 1887 Ripley, Derbyshire, Englandd. 30 October 1979 Leatherhead, Surrey, England[br]English aeronautical designer and inventor.[br]Wallis was apprenticed first at Thames Engineering Works, and then, in 1908, at John Samuel White's shipyard at Cowes. In 1913, the Government, spurred on by the accelerating development of the German Zeppelins (see Zeppelin, Ferdinand von), ordered an airship from Vickers; Wallis was invited to join the design team. Thus began his long association with aeronautical design and with Vickers. This airship, and the R80 that followed it, were successfully completed, but the military lost interest in them.In 1924 the Government initiated a programme for the construction of two airships to settle once and for all their viability for long-dis-tance air travel. The R101 was designed by a Government-sponsored team, but the R100 was designed by Wallis working for a subsidiary of Vickers. The R100 took off on 29 July 1930 for a successful round trip to Canada, but the R101 crashed on its first flight on 4 October, killing many of its distinguished passengers. The shock of this disaster brought airship development in Britain to an abrupt end and forced Wallis to direct his attention to aircraft.In aircraft design, Wallis is known for his use of geodesic construction, which combined lightness with strength. It was applied first to the single-engined "Wellesley" and then the twin-en-gined "Wellington" bomber, which first flew in 1936. With successive modifications, it became the workhorse of RAF Bomber Command during the Second World War until the autumn of 1943, when it was replaced by four-engined machines. In other areas, it remained in service until the end of the war and, in all, no fewer than 11,461 were built.Wallis is best known for his work on bomb design, first the bouncing bomb that was used to breach the Möhne and Eder dams in the Ruhr district of Germany in 1943, an exploit immortalized in the film Dambusters. Encouraged by this success, the authorities then allowed Wallis to realize an idea he had long urged, that of heavy, penetration bombs. In the closing stages of the war, Tallboy, of 12,000 lb (5,400 kg), and the 10-ton Grand Slam were used to devastating effect.After the Second World War, Wallis returned to aeronautical design and was given his own department at Vickers to promote his ideas, principally on variable-geometry or swing-wing aircraft. Over the next thirteen years he battled towards the prototype stage of this revolutionary concept. That never came, however; changing conditions and requirements and increasing costs led to the abandonment of the project. Bit-terly disappointed, Wallis continued his researches into high-speed aircraft until his retirement from Vickers (by then the British Aircraft Corporation), in 1971.[br]Principal Honours and DistinctionsKnighted 1968.
