Igor I. Sikorsky

Died 26 Oct 1972 at age 83 (born 25 May 1889).Igor Ivan Sikorsky was a Russian-born U.S. pioneer in aircraft design who is best known for his successful development of the helicopter. His earliest successes were with fixed-wing aircraft, including his prize-winning S-6-A (1912) which led to a position as head of the aviation subsidiary of the Russian Baltic Railroad Car Works. In this position, as a result of a mosquito-clogged carburetor and subsequent engine failure, he had the radical idea of an aircraft having more than one engine. Thus he produced the first multi-engine airplane, the four-engined "The Grand." This revolutionary aircraft featured such things as an enclosed cabin. a lavatory, upholstered chairs and an exterior catwalk atop the fuselage so passengers could take a turn about in the air.[Image: from U.S. airmail postage stamp]
