Fascinated by science and innovation, Lamarr’s “hobby” as an inventor led her to develop a radio guidance system intended for Allied torpedoes. The spread spectrum and frequency aspects of that work presaged today’s Bluetooth and WiFi technologies. She was inducted into the National Inventors Hall of Fame in 2014 but Lamarr’s pursuits were rarely taken seriously in their time.
She was a sensation during the “Golden Age” of MGM with films such as Algiers, Boom Town, Lady of the TropicsandTortilla Flat. Lamarr, who had six divorces by age 51, had a wry view of her love life: “I’ve never liked bargains when it came to sex.” The actress and inventor died in January 2000 at age 85.
