HedyLamarr

Hedy Lamarr (/ˈhɛdi/; born Hedwig Eva Maria Kiesler, 9 November 1914 – 19 January 2000)[a] was an Austrian and American actress and inventor.[1] After an early film career in Germany, which culminated in her controversial nude scenes in the film Ecstasy (1933), Lamarr moved to Hollywood at the invitation of MGM head Louis B. Mayer, and soon became a star during the studio's golden age.[2]

In Hollywood, Lamarr began inventing. Her most significant contribution to technology was her co-invention, with composer George Antheil, of an early technique for spread spectrum communications and frequency hopping,[3] which paved the way for today's wireless communications.[4][5] The invention in 1941 was deemed so vital to national defense that government officials would not allow publication of its details.[6] At the Electronic Frontier Foundation's Sixth Pioneer Awards in 1997, she and George Antheil were honored with special awards for their "trail-blazing development of a technology that has become a key component of wireless data systems", and in 2014 Lamarr was inducted into the National Inventors Hall of Fame.[3][7] -Wikipedia
