Hedwig Eva Maria Kiesler, known as Hedy Lamarr (Vienna, November 9, 1914n 1-Casselberry, Florida, January 19, 2000), was an Austrian film actress and inventor. She was a co-inventor, along with George Antheil, of the first version of spread spectrum that would allow long-distance wireless communications.
At the start of World War II, she and composer George Antheil developed a patent for a radio guidance system for Allied torpedoes that used spread spectrum and frequency hopping technology to defeat the threat of interference from the powers. From the axis. Although the United States Navy did not adopt the technology until the 1960s, the principles of its work were tied to Bluetooth technology and are similar to the methods used in legacy versions of Wi-Fi. This work led to his induction into the National Inventors Hall of Fame in 2014.
