Hedy Lamarr in Her Highness and the Bellboy trailer

Hedy Lamarr (1914–2000), Austrian-born American film star who was often typecast as a provocative femme fatale. Years after her screen career ended, she achieved recognition as a noted inventor of a radio communications device. The daughter of a prosperous Viennese banker, Lamarr was privately tutored from age 4; by the time she was 10, she was a proficient pianist and dancer and could speak four languages. At age 16 she enrolled in Max Reinhardt’s Berlin-based dramatic school, and within a year she made her motion picture debut in Geld auf der Strasse (1930; Money on the Street). She achieved both stardom and notoriety in the Czech film Extase (1932; Ecstasy), in which she briefly but tastefully appeared in the nude. Her burgeoning career was halted by her 1933 marriage to Austrian munitions manufacturer Fritz Mandl, who not only prohibited her from further stage and screen appearances but also tried unsuccessfully to destroy all existing prints of Extase. After leaving the possessive Mandl, she went to Hollywood in 1937, where she appeared in her first English-language film, the classic romantic drama Algiers (1938). Lamarr became a U.S. citizen in 1953.
