Hedy Lamarr: Movie star who paved way for Wi-Fi
Lamarr was born Hedwig Eva Maria Kiesler in 1914 in Vienna, the only child of Gertrud "Trude" Kiesler and Emil Kiesler . Her mother was a pianist and father a banker.
The woman many critics and fans alike regard as the most beautiful ever to appear in films.
Her most significant technological contribution was her co-invention, together with with composer George Antheil, of an early technique for spread spectrum communications and frequency hopping, which paved the way for today's wireless communications.
It was Hedy's idea for a secret communications system - specifically one that could guide a torpedo using a technology called "frequency hopping" - so that signal couldn't be intercepted.
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.
