Hedy Lamarr born in , November 9, 1914 was an Austrian and American film actress and inventor.
After an early and brief film career in Czechoslovakia that included the controversial film Ecstasy (1933 – in which Lamarr is very briefly seen swimming in the nude and running naked), she fled from her husband, a wealthy Austrian ammunition manufacturer, and secretly moved to Paris. There, she met MGM head Louis B. Mayer, who offered her a movie contract in Hollywood, where she became a film star from the late 1930s to the 1950s.
Hedy Lamarr, once dubbed "the most beautiful woman in the world", was a lonely movie star who fled Austria to the US during the war. She was so lonely, in fact, that she spent her evenings alone, surrounded by engineering books, inventing everything from a better tissue box to a new traffic signal.But it was her system of frequency hopping that she invented during World War II to assist the US Navy, that is still used today in wireless communications technology like Bluetooth, GPS, and Wi-Fi.
In short she was the real example of beauty with brain !!!
