Hedy Lamarr

Hedy Lamarr (9 November 1914 – 19 January 2000) was an Austrian-born American film actress and inventor. A film star during Hollywood's golden age, Lamarr has been described as one of the greatest movie actresses of all time.
After a brief film career in Europe, including "Ecstasy" (1933), Lamar moved to the United States. 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." (1941), and "White Cargo" (1942). Her greatest success was as Delilah in "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, she and avant-garde composer George Antheil developed a radio guidance system for Allied torpedoes that used spread spectrum and frequency hopping technology to defeat the threat of jamming by the Axis powers.
Life.
Hedy Lamarr was born as Hedwig Eva Maria Kiesler in Vienna. She was the daughter of a bank director and a concert pianist. She studied ballet and piano at age 10. 
Later, the famous director Max Reinhard in Berlin said she was the most beautiful woman in Europe. She worked in movies and in her third movie played her first title role ("Man braucht kein Geld" or "No Money Needed"). The 1933 movie "Ecstasy" was considered a scandal as it showed her bathing naked and running through a wood naked. Later that year, she married, but left her husband in 1937. She signed a contract with MGM in London and went to the USA, where she became a film star and spent the rest of her life. With a musician friend she patented a torpedo to be controlled by spread spectrum radio signals. She became a US citizen in 1953. She died in Altamonte Springs, Florida.
