January 19th, 2023 marks the twenty-third anniversary of the passing of Hollywood actress Hedy Lamarr. Once named "the most beautiful woman in film" by Louis B. Mayer, the head of MGM studios, Lamarr was an American movie star during the Golden Age of film, known for her stunning beauty and a string of successful films and television appearances, up until her retirement in 1958. What many people don't know is that Lamarr was also a successful inventor. In fact, her invention of a "secret communication system" helped pave the way for our modern day technologies of GPS and Bluetooth wireless communication.
