Evidence Performed by Hedy Lamarr

  • Name
    Invention of Frequency-Hopping Spread Spectrum Technology
  • Description

    Determined to aid the Allied war effort, Hedy noticed that standard radio-guided torpedoes could easily be disabled by enemy broadcasting interference. She conceived a solution using randomized frequency shifts and partnered with avant-garde composer George Antheil to synchronize these changes using 88-note player-piano paper rolls. They successfully mapped out a secure system and were granted US Patent 2,292,387, delivering an architecture that laid the foundations for all future secure wireless networking.
