Hedy Lamarr, born Hedwig Eva Maria Kiesler (9 November 1914 – 19 January 2000) was an Austrian-American film actress and inventor. Often called “The Most Beautiful Woman in Films”, Hedy Lamarr’s beauty and screen presence made her one of the most popular actresses of her day.
At the beginning of World War II, Lamarr 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 now incorporated into modern Wi-Fi, CDMA, and Bluetooth technology, and this work led to their induction into the National Inventors Hall of Fame in 2014.
