One evening in the early 1940s, the pair discovered a remarkable technique called “frequency hopping.” Their invention would allow allied torpedoes to strike their targets without being thwarted by radio jamming, which obviously attracted a great deal of interest from the US Navy.

Frequency hopping played a significant role in WWII and was eventually used to develop Wi-Fi, Bluetooth, and GPS. American actress Hedy Lamarr may not have literally invented WiFi - that honor goes to Australian boffin John O'Sullivan - but she did discover a pretty important precursor.
