A contracted MGM actress, Hedy Lamarr was initially known for her beauty and roles opposite legendary actors including Clark Gable. She grew bored of the Hollywood scene and spent her time with science experiments. In an effort to help the Allies during World War II, Hedy and a friend presented the US Navy with their patent on a "spread-spectrum radio" designed to guide torpedoes accurately. It's now looked at as a precursor to today's wireless technology.
