Hedy Lamarr was an actress and inventor. After an early and brief film career in Czechoslovakia that included the controversial film Ecstasy (1933 – in which Lamarr is very briefly seen swimming in the nude and running naked), she fled from her husband, a wealthy Austrian ammunition manufacturer, and secretly moved to Paris. There, she met MGM 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.
