Hedy Lamar (1914-2000) was beautiful, bold and inventive. An Austrian actress who emigrated to the U.S. and became a movie star, she was also an inventor. At the beginning of WWII, with the aid of composer George Antheil, she proposed a method to prevent the Germans from jamming Allied radio communications. Although her proposed spread spectrum and frequency hopping technology was not adopted by the U.S. military until the 1960s, her theory was eventually instrumental in the development of Wi-Fi, CDMA and Bluetooth technology.
