1913 - 2000 (Austria, U.S.A.)
The only child of an Austrian bank-director father and a classically trained pianist mother, Hedy Lamarr enjoyed a successful early career in Post WW1 Austrian theatre and film. She escaped an unhappy marriage to a Nazi sympathizer and was brought to the US in 1937 by film mogul Louis B Mayer, who named her "The World’s Most Beautiful Woman." Her career spanned more than 30 movies made over nearly three decades.
Bored with her declining career, Hedy turned her attention to applied sciences. With the help of composer George Antheil, she designed a jam-proof radio guidance system for torpedoes creating technology they later patented.
Hedy’s development of spread spectrum and frequency hopping technology aided the US Navy’s WW2 efforts and principals of her work are incorporated into modern GPS, WI-FI, CDMA (cell phone), and Bluetooth technology.
