November 9, the Google Doodle (on Google’s home page) celebrated the birthday of Hedy Lamarr, born Hedwig Eva Maria Kiesler, 9 November 1914 – 19 January 2000.
She is most known for being a beautiful movie star, but she was also a talented inventor who helped develop spread spectrum frequency hopping technology, used in World War II. Though the US Navy did not adopt the technology until the 1960s, the principles of her work are now incorporated into modern Wi-Fi, CDMA and Bluetooth technology.
