Hedy Lamarr at Wikipedia:

Lamarr’s most significant contribution to technology was her co-invention, with composer George Antheil, of an early technique for spread spectrum communications and frequency hopping, which paved the way for today’s wireless communications. The invention in 1941 was deemed so vital to national defense that government officials would not allow publication of its details. At the Electronic Frontier Foundation’s Sixth Pioneer Awards in 1997, she and George Antheil were honoured with special awards for their “trail-blazing development of a technology that has become a key component of wireless data systems”
