Many knew Hedy Lamarr as a famous Hollywood actress, but even more impressive is that she was a self-taught inventor. She invented an extraordinary new communication system with the intention of guiding torpedoes to their targets in World War II.
The system involved the use of “frequency hopping” amongst radio waves, with both transmitter and receiver hopping to new frequencies together. Doing so prevented the interception of the radio waves, thereby allowing the torpedo to find its intended target.
The American Navy decided against the implementation of the new system, but the invention has since brought incredible value to the modern society, as it is being used in wireless communication such as WiFi, Bluetooth and GPS.
Although Hedy Lamarr passed away in 2000, she was inducted into the National Inventors Hall of Fame for the development of her frequency hopping technology in 2014.
