HEDY! The Life & Inventions of Hedy Lamarr explores Hedy Lamarr’s Hollywood stardom and inventive achievements in the war effort. A Viennese-born film star of the 1930s to 1950s known as “The Most Beautiful Woman in the World,” Lamarr stored away knowledge of munitions while married to Austrian arms dealer, Friedrich “Fritz” Mandl. She employed this knowledge to support the US Navy’s war effort during World War II by inventing The Secret Communication System with composer George Antheil, which made torpedoes more accurate. Also referred to as frequency-hopping spread spectrum technology, her invention is used today in cell phones, Wi-Fi, CDMA, GPS, Bluetooth, and a myriad of other wireless systems.
