After a brief early film career in Czechoslovakia, including the controversial Ecstasy 1933 she fled from her first husband, a wealthy Austrian ammunition manufacturer, and secretly moved to Paris. Traveling to London, she met Metro-Goldwyn-Mayer studio head Louis B. Mayer, who offered her a movie contract in Hollywood. She became a film star with her performance in Algiers 1938 Her MGM films include Lady of the Tropics 1939, Boom Town 1940, H.M. Pulham Esq and White Cargo 1942. Her greatest success was as Delilah in Cecil B. DeMilles Bible-inspired Samson and Delilah 1949. She also acted on television before the release of her final film, The Female Animal 1958. She was honored with a star on the Hollywood Walk of Fame in 1960. Hedy Lamarr was a famous Hollywood actress and a brilliant inventor who made significant contributions to the field of wireless communication. She co-invented a technique called frequency hopping, which is the basis of modern technologies such as WiFi, Bluetooth, and GPS. Frequency hopping is a method of transmitting radio signals by rapidly switching among many frequency channels, using a pseudorandom sequence known to both transmitter and receiver. This makes the communication more secure and resistant to interference, jamming, and detection. Lamarr came up with the idea of frequency hopping during World War II, when she wanted to help the US Navy develop a radio-guided torpedo that could not be easily jammed by the enemy. She collaborated with composer George Antheil, who suggested using a piano roll to synchronize the frequency changes between the transmitter and the receiver. They patented their invention in 1942, but it was not adopted by the US military until the 1960s, when it was used in naval communication systems. Lamarr and Antheil did not receive any recognition or compensation for their work until 1997, when they were awarded the Electronic Frontier Foundation Pioneer Award. Lamarr also became the first female recipient of the BULBIE™ Gnass Spirit of Achievement Award, which is considered the “Oscars” of inventing.
