Hedy Lamarr the bombshell movie star was also an inventor. She realized that by transmitting radio signals along rapidly changing, or "hopping," frequencies, American radio-guided weapons would be far more resilient to detection and jamming. She invented and patented frequency hopping which the navy promptly rejected. The technology was far ahead of its time and was rejected most likely because she was a movie star and even worse, a woman.
Although her ideas were at first ignored, the technology (which she and an avant-garde composer George Antheil patented in 1942) was later used by the military. More recently, it has been employed in wireless technologies like cell phones, Bluetooth and WiFi.
It was eventually recognized in 1997, when the Electronic Frontier Foundation honored Lamarr with a special Pioneer Award and she became the first woman to receive the Invention Convention's BULBIE Gnass Spirit of Achievement Award. Upon hearing of her award, Hedy responded, “It’s about time.” An off-Broadway play, Frequency Hopping, tells the story of her collaboration and friendship with Antheil. The Discovery Channel and Science Channel have both broadcast specials about her talents as an inventor, and Google has honored her with a doodle.
