After a brief early film career in Czechoslovakia, she fled from her husband, a wealthy Austrian ammunition manufacturer, and secretly moved to Paris. There, 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).
Lamarr is also credited with being an inventor. At the beginning of World War II, she and composer George Antheil developed a radio guidance system for Allied torpedoes, which used spread spectrum and frequency hopping technology to defeat the threat of jamming by the Axis powers.
Although the US Navy did not adopt the technology until the 1960s, the principles of their work are arguably incorporated into Bluetooth technology, and are similar to methods used in legacy versions of CDMA and Wi-Fi.
Lamarr was married six times, had two sons and a daughter. She died in 2000 in Casselberry, Florida, of heart disease, aged 85.
