Hedy Lamarr was one of the most famous actresses of the Golden Age of Hollywood. She starred in 18 films during the 1940's. A little known fact about Lamarr, however, is that she played a significant role in the remote control of everything from torpedoes to wifi.
Early in her acting career, Lamarr married an Austrian arms manufacturer name Friedrich Mandl. Mandl did not approve of Lamarr's acting career and would often take her to business meetings with him. From these meetings, the mathematically gifted Hedy learned about military technology.
In 1941, she paired with German composer George Antheil to create a wireless system of musical instruments. The radio technology they developed could also be used by the military to remotely control torpedoes. Their work was not received with great attention until the advent of later technologies such as cordless phones and wireless internet connection. The so called frequency hopping makes the connection you're on right now more secure.
