Hedy Lamarr

Hedy Lamarr (born Hedwig Eva Maria Kiesler; November 1914 – 19 January 2000), was an American actress, inventor, and film producer. She appeared in 30 films over a 28-year career, and co-invented an early version of frequency-hopping spread spectrum communication for torpedo guidance.Lamarr was born in Vienna, Austria-Hungary, and acted in a number of Austrian, German, and Czech films in her brief early film career, including the controversial Ecstasy (1933). In 1937, she fled from her husband, a wealthy Austrian ammunition manufacturer, secretly moving to Paris and then on to London. There she met Louis B. Mayer, head of Metro-Goldwyn-Mayer (MGM) studio, who offered her a Hollywood movie contract, where he began promoting her as "the world's most beautiful woman". She became a star through her performance in Algiers (1938), her first American film. She starred opposite Clark Gable in Boom Town and Comrade X (both 1940), and James Stewart in Come Live with Me and Ziegfeld Girl (both 1941). Her other MGM films include Lady of the Tropics (1939), H.M. Pulham, Esq. (1941), as well as Crossroads and White Cargo (both 1942); she was also borrowed by Warner Bros. for The Conspirators, and by RKO for Experiment Perilous (both 1944). Dismayed by being typecast, Lamarr co-founded a new production studio and starred in its films: The Strange Woman (1946), and Dishonored Lady (1947). Her greatest success was as Delilah in Cecil B. DeMille's 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. At the beginning of World War II, Lamarr and composer George Antheil developed a radio guidance system using frequency-hopping spread spectrum technology for Allied torpedoes, intended to defeat the threat of jamming by the Axis powers. She also helped improve aircraft aerodynamics for Howard Hughes while they dated during the war. Although the US Navy did not adopt Lamarr and Antheil's invention until 1957, various spread-spectrum techniques are incorporated into Bluetooth technology and are similar to methods used in legacy versions of Wi-Fi. Recognition of the value of their work resulted in the pair being posthumously inducted into the National Inventors Hall of Fame in 2014.
