Born in Vienna as Hedwig Kiesler, she gained early fame in European cinema. The drummed colleagues.
- MGM brought her to the U.S., where she became the defining faces of the Golden Age of Hollywood.
- Known for films such as Algiers (1938), Ziegfeld Girl (1941), and Samson and Delilah (1949).
- Often publicized as “the most beautiful woman in the world,” which ironically overshadowed her scientific mind.
Hedy Lamarr teamed up with composer George Antheil during World War II to develop a secure torpedo-guidance system.
They invented frequency-hopping spread spectrum, a method of rapidly changing radio frequencies to prevent enemy jamming.
This technology:
- Was patented in 1942
- Was initially ignored by the U.S. Navy
- Later became foundational for Bluetooth, Wi-Fi, GPS, and modern encrypted communications
Lamarr received little recognition at the time because military innovations by civilians — especially women — weren’t taken seriously.
Frequency hopping prevented signals from being intercepted or jammed — a revolutionary idea during wartime.
Today, her conceptual leap is embedded in virtually every wireless device.
- In 1997, she received the Electronic Frontier Foundation (EFF) Pioneer Award.
- Also honored by the U.S. government for her contribution to national security.
- Many retrospectives now regard her as a visionary technologist as well as a film legend
Hedy Lamarr’s story is one of dramatic contrasts:
- A glamorous actress who sketched inventions in her trailer between filming scenes
- A woman dismissed in her own time, but whose scientific legacy is now central to modern communication
- A reminder that genius and beauty are not mutually exclusive — but that society often struggles to see both at once
