Hedy Lamarr: The Inventive Actress Who Revolutionized Wireless Tech

Hedy Lamarr was more than a silver-screen star; she was a brilliant mind whose groundbreaking invention laid the foundation for today’s wireless technologies. Born in Vienna in 1914, she defied expectations, challenging stereotypes of actresses as mere performers by pursuing science with relentless curiosity.

Lamarr’s journey into invention began during World War II, when she collaborated with composer George Antheil to develop a frequency-hopping system designed to prevent enemy jamming of radio-controlled torpedoes. Though initially overlooked by military authorities, their patent from 1942 became a cornerstone of modern spread-spectrum communication. This innovation directly influenced Wi-Fi, Bluetooth, and GPS—technologies now integral to daily life.

What makes Lamarr’s story remarkable is her dual legacy: a celebrated actress by daytime and a visionary inventor by night. Her work exemplifies how creativity and technical insight can converge to change the world. Despite limited recognition during her lifetime, recent years have seen a resurgence of interest, with museums, tech conferences, and educational programs honoring her contributions.
