Composer. The son of German immigrants, he gained fame as pianist and composer in the avant-garde genre. His trademark work was the 1924 work "Le Ballet Mecanique", which incorporated sounds from machines like airplane propellers and car horns. He also wrote film scores for numerous movies in the 1930s. At a dinner party given by Janet Gaynor, George Antheil met Hedy Lamarr. Shortly after this meeting, Lamarr and Antheil invented and patented a secret communications system, U.S. Patent 2,292,387. The patent was applied for June 10, 1941, and received August 11th, 1942. The purpose of the system was to provide reliable and jam proof control of long range torpedoes. The system involved the use of the frequency hopping principles of Spread Spectrum radio. However it was 20 years before it was put to effective use by the United States Navy in torpedo guidance systems, and 40 years before it was permitted by the FCC to be used in commercial radios. Among other things, Spread Spectrum forms the basic principle that allows the use of simultaneous multi-channel operation used in modern digital cellular telephone systems. Spread spectrum is the basis for the communications security of the strategic $25 billion MILSAT Defense communications system.
