Hedwig Eva Maria Kiesler
Born in Vienna in 1914, Hedwig Eva Maria Kiesler was an Austrian-American actress and inventor.

She became Hedy Lamarr after meeting head of MGM Studios Louis B. Meyer and was offered a Hollywood movie contract. She acted in several features from the late 1930s to the 1950s.

At the beginning of World War II, she paired up with composer George Antheil to develop a radio guidance system for Allied torpedoes. Since torpedoes had a relatively high chance of getting jammed and going off course, the frequency hopping spread spectrum system (which consisted of continuously changing radio signals) was meant to more clearly and effectively "guide" the torpedoes.

The patented invention paved the way for modern use of technologies for WiFi, CDMA, and Bluetooth.

Hedy Lamarr died on January 19th, 2000.

Lamarr and Antheil were posthumously inducted in the National inventors Hall of Fame in 2014.
