101 Cousteau, Jacques-Yves
SUBJECT AREA: Ports and shipping[br]b. 11 June 1910 Saint-André-de-Cubzac, France[br]French marine explorer who invented the aqualung.[br]He was the son of a country lawyer who became legal advisor and travelling companion to certain rich Americans. At an early age Cousteau acquired a love of travel, of the sea and of cinematography: he made his first film at the age of 13. After an interrupted education he nevertheless passed the difficult entrance examination to the Ecole Navale in Brest, but his naval career was cut short in 1936 by injuries received in a serious motor accident. For his long recuperation he was drafted to Toulon. There he met Philippe Tailliez, a fellow naval officer, and Frédéric Dumas, a champion spearfisher, with whom he formed a long association and began to develop his underwater swimming and photography. He apparently took little part in the Second World War, but under cover he applied his photographic skills to espionage, for which he was awarded the Légion d'honneur after the war.Cousteau sought greater freedom of movement underwater and, with Emile Gagnan, who worked in the laboratory of Air Liquide, he began experimenting to improve portable underwater breathing apparatus. As a result, in 1943 they invented the aqualung. Its simple design and robust construction provided a reliable and low-cost unit and revolutionized scientific and recreational diving. Gagnan shunned publicity, but Cousteau revelled in the new freedom to explore and photograph underwater and exploited the publicity potential to the full.The Undersea Research Group was set up by the French Navy in 1944 and, based in Toulon, it provided Cousteau with the Opportunity to develop underwater exploration and filming techniques and equipment. Its first aims were minesweeping and exploration, but in 1948 Cousteau pioneered an extension to marine archaeology. In 1950 he raised the funds to acquire a surplus US-built minesweeper, which he fitted out to further his quest for exploration and adventure and named Calypso. Cousteau also sought and achieved public acclaim with the publication in 1953 of The Silent World, an account of his submarine observations, illustrated by his own brilliant photography. The book was an immediate success and was translated into twenty-two languages. In 1955 Calypso sailed through the Red Sea and the western Indian Ocean, and the outcome was a film bearing the same title as the book: it won an Oscar and the Palme d'Or at the Cannes film festival. This was his favoured medium for the expression of his ideas and observations, and a stream of films on the same theme kept his name before the public.Cousteau's fame earned him appointment by Prince Rainier as Director of the Oceanographie Institute in Monaco in 1957, a post he held until 1988. With its museum and research centre, it offered Cousteau a useful base for his worldwide activities.In the 1980s Cousteau turned again to technological development. Like others before him, he was concerned to reduce ships' fuel consumption by harnessing wind power. True to form, he raised grants from various sources to fund research and enlisted technical help, namely Lucien Malavard, Professor of Aerodynamics at the Sorbonne. Malavard designed a 44 ft (13.4 m) high non-rotating cylinder, which was fitted onto a catamaran hull, christened Moulin à vent. It was intended that its maiden Atlantic crossing in 1983 should herald a new age in ship propulsion, with large royalties to Cousteau. Unfortunately the vessel was damaged in a storm and limped to the USA under diesel power. A more robust vessel, the Alcyone, was fitted with two "Turbosails" in 1985 and proved successful, with a 40 per cent reduction in fuel consumption. However, oil prices fell, removing the incentive to fit the new device; the lucrative sales did not materialize and Alcyone remained the only vessel with Turbosails, sharing with Calypso Cousteau's voyages of adventure and exploration. In September 1995, Cousteau was among the critics of the decision by the French President Jacques Chirac to resume testing of nuclear explosive devices under the Mururoa atoll in the South Pacific.[br]Principal Honours and DistinctionsLégion d'honneur.

102 Nipkow, Paul Gottlieb
[br]b. 22 August 1860 Lauenburg, Pommern (now Lebork, Poland)d. 24 August 1940 Berlin, Germany[br]Polish electrical engineer who invented the Nipkow television scanning disc.[br]In 1884, while still a student engineer, Nipkow patented a mechanical television pick-up device using a disc with a spiral of twenty-four holes rotating at 600 rpm in front of a selenium cell. He also proposed a display on an identical synchronous disc in conjunction with a light-modulator based on the Faraday effect. Unfortunately it was not possible to realize a working system at the time because of the slow response of selenium cells and the lack of suitable electronic-sig-nal amplifiers; he was unable to pay the extension fees and so the patent lapsed. Others took up the idea, however, and in 1907 pictures were sent between London and Paris by wire. Subsequently, the principle was used by Baird, Ives, and Jenkins.For most of his working life after obtaining his doctorate, Nipkow was employed as an engineer by a company that made railway-signalling equipment, but his pioneering invention was finally recognized in 1934 when he was made Honorary President of the newly formed German Television Society.[br]Principal Honours and DistinctionsPresident, German Television Society 1934.Bibliography1884, German patent no. 30,105 (Nipkow's pioneering method of television image-scanning).Further ReadingR.W.Hubbell, 1946, 4,000 Years of Television, London: G.Harrap \& Co.KF
