Popular actress of the ’40s and often dubbed the most beautiful woman of her time, Hedy Lamarr had a lot going for her. At the age of 19, she starred in the Czech movie Ecstasy (1933), the first known (non-pornographic) film to show sex, nudity and to have a woman to orgasm. Tame to these days standards, the film caused uproar in the US, and the state of Pennsylvania even banned it once it was finally released. The film got her recognised by Hollywood, but her acting alone didn’t give her the legacy she deserves. On the side of her acting career, she also helped develop a radio communications system wanting to aid the allied forces against the Germans in 1941. Little did she know it would be the foundation for Wi-Fi and Bluetooth.
