Hedy Lamarr - Biography
Was co-inventor (with composer George Antheil) of the earliest known form of the telecommunications method known as "frequency hopping", which used a piano roll to change between 88 frequencies and was intended to make radio-guided torpedoes harder for enemies to detect or to jam. The method received U.S. patent number 2,292,387 on Aug. 11, 1942, under the name "Secret Communications System". Frequency hopping is now widely used in cellular phones and other modern technology. However neither she nor Antheil profited from this fact, because their patents were allowed to expire decades before the modern wireless boom. She received an award from the Electronic Frontier Foundation in 1997 for her work pioneering work in spread-spectrum technology.
