I knew that Lamarr was an inventor, but I did not know the details. This is so cool! After Lamar met composer George Antheil, who had been experimenting with automated control of musical instruments, together they hit on the idea of frequency hopping. At the time, radio-controlled torpedoes could easily be detected and jammed by broadcasting interference at the frequency of the control signal, thereby causing the torpedo to go off course. Frequency hopping essentially served to encrypt the control signal because it was impossible for a target to scan and jam all of the frequencies.
