Who is actor and inventor Hedy Lamarr?
Hedy Lamarr was the stage name of Hedwig Eva Maria Kiesler, an Austrian-born American actor and inventor born on November 9, 1914, in Vienna, then part of Austria-Hungary. Known for her Hollywood film career from the 1930s through the 1950s, she was also a co-inventor of a frequency-hopping communication system that later became associated with developments in wireless technology.
Background/biography
Lamarr was born to Emil Kiesler, a bank director, and Gertrud Lichtwitz Kiesler, a pianist. She grew up in Vienna and developed an interest in performing at an early age. After attending school in Vienna, she pursued acting training, including study associated with theater director Max Reinhardt in Berlin.
She began appearing in European films while still young and gained international attention for her role in the 1933 film Ecstasy. In 1937, she moved to the United States and signed with Metro-Goldwyn-Mayer, where studio head Louis B. Mayer promoted her under the name Hedy Lamarr.
Film career and inventions
- Ecstasy (1933)
- Algiers (1938)
- Lady of the Tropics (1939)
- Boom Town (1940)
- Comrade X (1940)
- Ziegfeld Girl (1941)
- Samson and Delilah (1949)
- U.S. Patent No. 2,292,387, a “secret communication system” developed with composer George Antheil and granted in 1942
Lamarr became one of Hollywood’s most recognizable stars during the studio era, appearing opposite actors including Charles Boyer, Clark Gable, Spencer Tracy, James Stewart, and Victor Mature. Her 1949 film Samson and Delilah, directed by Cecil B. DeMille, was among the major commercial successes of its period.
During World War II, Lamarr and Antheil developed a system designed to help prevent radio-guided torpedoes from being jammed. Their patented concept used changing radio frequencies in coordination, an approach now commonly described as frequency hopping. The system was not widely adopted by the U.S. military during the war, but the underlying principles were later recognized as relevant to spread-spectrum and wireless communications technology.
Recognition beyond Hollywood
Lamarr’s work as an inventor received broader public recognition later in life. In 1997, she and George Antheil received the Electronic Frontier Foundation’s Pioneer Award. Lamarr was inducted into the National Inventors Hall of Fame posthumously in 2014 for the frequency-hopping patent she shared with Antheil.
