Born in 1914, Hedy Lamarr was a famous American actress who pioneered the technology that would lead to WiFi, GPS, cell phones & Bluetooth communication.

Lamarr was brilliant. Among many fascinating inventions, she developed a new communication system with composer George Antheil that used “frequency hopping” among radio waves.

Once called the “most beautiful woman in the world," Lamarr is now remembered as "the mother of Wi-Fi."

Frequency hopping was invented during WW II and initially had a military application, for instance in the guidance system of torpedos. Frequency hopping prevented the guidance system to be jammed by the axis powers, as it was rendered impossible to “guess” the right frequency. So Hedy #Lamarr was also a war hero - although unaknowledged because her work had to be kept top secret during the war.
