Hedy Lamarr's story is not an uncommon one in the glamourous and tumultuous world of Hollywood's golden age. Called "the most beautiful woman in Europe", the Austrian woman filmed a controversial sex scene in Germany in 1933, ran away from her husband to move to Paris, and signed a contract with MGM head Louis B. Mayer himself. Alongside her acting career, Hedy Lamarr alleviated her growing boredom as an inventor. In 1942 she patented something called a 'frequency-hopping spread spectrum' -- the precursor to modern Wi-Fi and Bluetooth technology.
