Hollywood actress[edit]
After escaping her estranged husband, she fled to Paris in 1937, where she met Louis B. Mayer, who was scouting for talent in Europe.[16] Mayer hired her but later wanted her to change her name to Hedy Lamarr—she had been known as "the Ecstasy lady"[15]—choosing the surname in homage to the beautiful silent film star, Barbara La Marr. Upon arriving in Hollywood in 1938, Mayer began promoting her as the "world's most beautiful woman."[17]

With the ongoing World War, Lamarr was inspired to contribute to the war effort by designing a jam-proof radio guidance system for torpedoes. With the help of composer George Antheil, they drafted designs for a new frequency-hopping spread-spectrum technology that they later patented.[19]
Lamarr and Antheil realized that radio-controlled torpedoes, which could be important in the naval war, could easily be jammed, thereby causing the torpedo to go off course.[20] With the knowledge she had gained about torpedoes from her first husband, and using a method similar to the way piano rolls work, they designed a frequency-hopping system that would continually change the radio signals sent to the torpedo.[21]
