Hedy Lamarr was young, talented, and so beautiful that she was called "the most beautiful woman in the world." She fled her native Austria after the Nazi occupation, as well as her first husband, an arms dealer, only to end up in 1940s Hollywood, where the film industry was run exclusively by men. The incredibly attractive actress found it hard to be valued for anything but her looks. But Hedy wasn't just a beauty: she was also curious and smart. She loved coming up with inventions, and developed an encrypted communications system later used for missile guidance and also wi-fi. The exceptional life of an extraordinary woman.
