1942: Austrian-American actress and inventor Hedy Lamarr and composer George Antheil developed a radio guidance system for Allied torpedoes that used spread spectrum and frequency hopping technology to defeat the threat of jamming by the Axis powers.
Hedy Lamarr and co-inventor, George Antheil, worked on a frequency hopping method to help the Navy control torpedoes remotely. [62] The Navy passed on their idea, but Lamarr and Antheil received a patent for the work on August 11, 1942. [62]
