Hedy Lamarr (born Hedwig Eva Maria Kiesler, November 9, 1914 – January 19, 2000) was an Austrian-born American film actress and inventor.
After a brief early film career in Czechoslovakia, including the controversial Ecstasy (1933), she fled from her 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, where she became a film star from the late 1930s to the 1950s. Among Lamarr's best known films are Algiers (1938), Boom Town (1940), I Take This Woman (1940), Comrade X (1940), Come Live With Me (1941), H.M. Pulham, Esq. (1941), and Samson and Delilah (1949).
Later, she was also known for her scientific researches during the war but she does not mention them in this autobiography.
