Hedy Lamarr helped to set the groundwork for some of the most revolutionary technology of our time.

Following the outbreak of World War II, Lamarr, a passionate opponent of the Nazis, wanted to contribute more to the allied effort. As Mrs. Fritz Mandl, she had closely observed the planning and discussions that went into attempting to design remote-controlled torpedoes. These never went into production, because the radio-controlled guidance system was too susceptible to disruption. She got the idea of distributing the torpedo guidance signal over several frequencies, thus protecting it from enemy jamming. The only weak point was how to employ the synchronization of the signal’s transmitter and receiver.
