Who is: Hedy Lamarr – WiFi, GPS & Bluetooth, technology

Did you know that Wi-Fi, GPS and Bluetooth, technology that allows us today to communicate in cyber space began as early as 1941? Yes, in another form - Let us at Recab present Hedy Lamarr mostly known for co-inventing an early version of frequency-hopping spread spectrum communication

Hedy Lamarr – WiFi, GPS & Bluetooth, technology
Hedy Lamarr was a famous actor, film producer and inventor. She is today mostly known for co-inventing an early version of frequency-hopping spread spectrum communication in 1941, then invented to protect Allied torpedo’s to be detected by theNazis. Today this technology is used in secure Wi-Fi, GPS and Bluetooth, technology that is used by millions of people all over the world. Read more about our selection of Network Communications

Secret communication system
Lamarr’s greatest scientific triumph was intended for the US navy during the second world war, but is now used in modern wireless communication. Her “secret communication system” used “frequency hopping” to guide radio-controlled missiles underwater in a way that was undetectable by the enemy. It was Lamarr’s brainwave (though some say she may have first seen a sketch of a similar idea in the office of her first husband, the Austrian munitions manufacturer Fritz Mandl) and she developed it together with a friend, the composer George Antheil. The patent was granted in 1942.

During her career she also contributed within the aircraft industry and helped improving aircraft aerodynamics. “Inventions are easy for me to do – I don’t have to work on ideas, they come naturally” Hedy said. And we are very grateful for that.
