Early Life

Hedy Lamarr was born on November 9, 1914, in Vienna, Austria. Her parents were Jewish, and her father was a successful bank director. Lamarr showed an early interest in acting and began appearing in small roles in Austrian films when she was a teenager.

Acting Career

In 1933, Lamarr appeared in the Czech film “Ecstasy,” which caused a scandal due to its nudity and sexual content. Despite the controversy, the film launched Lamarr’s career in Hollywood, and she went on to star in numerous films throughout the 1930s and 1940s.



During World War II, Lamarr worked with composer George Antheil to develop a radio guidance system that could be used to control torpedoes. The system used a frequency-hopping technique that made it difficult for enemies to jam the signal. Although the invention was not immediately put to use, it laid the foundation for modern wireless communication technologies like Wi-Fi and Bluetooth.
