BEAUTY & BRAINS

Submitted by ub on

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
