21 Sarnoff, David
[br]b. 27 February 1891 Uzlian, Minsk (now in Belarus)d. 12 December 1971 New York City, New York, USA[br]Russian/American engineer who made a major contribution to the commercial development of radio and television.[br]As a Jewish boy in Russia, Sarnoff spent several years preparing to be a Talmudic Scholar, but in 1900 the family emigrated to the USA and settled in Albany, New York. While at public school and at the Pratt Institute in Brooklyn, New York, he helped the family finances by running errands, selling newspapers and singing the liturgy in the synagogue. After a short period as a messenger boy with the Commercial Cable Company, in 1906 he became an office boy with the Marconi Wireless Telegraph Company of America (see G. Marconi). Having bought a telegraph instrument with his first earnings, he taught himself Morse code and was made a junior telegraph operator in 1907. The following year he became a wireless operator at Nantucket Island, then in 1909 he became Manager of the Marconi station at Sea Gate, New York. After two years at sea he returned to a shore job as wireless operator at the world's most powerful station at Wanamaker's store in Manhattan. There, on 14 April 1912, he picked up the distress signals from the sinking iner Titanic, remaining at his post for three days.Rewarded by rapid promotion (Chief Radio Inspector 1913, Contract Manager 1914, Assistant Traffic Manager 1915, Commercial Manager 1917) he proposed the introduction of commercial radio broadcasting, but this received little response. Consequently, in 1919 he took the job of Commercial Manager of the newly formed Radio Corporation of America (RCA), becoming General Manager in 1921, Vice- President in 1922, Executive Vice-President in 1929 and President in 1930. In 1921 he was responsible for the broadcasting of the Dempsey-Carpentier title-fight, as a result of which RCA sold $80 million worth of radio receivers in the following three years. In 1926 he formed the National Broadcasting Company (NBC). Rightly anticipating the development of television, in 1928 he inaugurated an experimental NBC television station and in 1939 demonstrated television at the New York World Fair. Because of his involvement with the provision of radio equipment for the armed services, he was made a lieutenant-colonel in the US Signal Corps Reserves in 1924, a full colonel in 1931 and, while serving as a communications consultant to General Eisenhower during the Second World War, Brigadier General in 1944.With the end of the war, RCA became a major manufacturer of television receivers and then invested greatly in the ultimately successful development of shadowmask tubes and receivers for colour television. Chairman and Chief Executive from 1934, Sarnoff held the former post until his retirement in 1970.[br]Principal Honours and DistinctionsFrench Croix de Chevalier d'honneur 1935, Croix d'Officier 1940, Croix de Commandant 1947.
