Hedy Lamarr: Hollywood Called Me Beautiful - Then I Co-Patented Frequency Hopping

Hedy Lamarr was famous as a Hollywood star, but this episode follows the stranger part of her story: during World War II, she worked with composer George Antheil on a frequency-hopping idea meant to protect radio-guided torpedoes from jamming.

Their patent was filed in 1941 and granted in 1942 as a "Secret communication system." The Navy did not build it at the time, but the idea later became part of the story behind modern wireless technologies such as Wi-Fi, GPS, and Bluetooth.
