An actress who performed along the greats like Judy Garland and Clark Gable in the Golden Age of Hollywood was so much more than a movie star.
It was Hedy’s idea for a secret communication system, specifically to guide torpedoes using “frequency hopping” during WWII.
Her invention is used for Wi-Fi, GPS, and most military communication.
She signed her patent over to the Navy who shelved the idea and told her to make money for the war instead of ‘silly inventing’. She never made a dime or got the credit she deserved.
