Hedy Lamarr, Movie Star and Inventor!

On This Day In History 1942 - American actress Hedy Lamarr and composer George Antheil received a patent for an electronic device that minimized the jamming of radio signals; it later became a component of satellite and cellular phone technology.

Lamarr shared her concept for using “frequency hopping” with the U.S. Navy and codeveloped a patent with Antheil 1941. Today, her innovation helped make possible a wide range of wireless communications technologies, including Wi-Fi, GPS, and Bluetooth.

Although Lamarr had no formal training and was primarily self-taught, she tinkered in her spare time on various hobbies and ideas, which included an improved traffic stoplight and a tablet that would dissolve in water to create a flavored carbonated drink.

During World War II, Lamarr read that radio-controlled torpedoes had been proposed. However, an enemy might be able to jam such a torpedo's guidance system and set it off course. When discussing this with her friend the composer and pianist George Antheil, the idea was raised that a frequency-hopping signal might prevent the torpedo's radio guidance system from being tracked or jammed. Antheil succeeded by synchronizing a miniaturized player piano mechanism with radio signals. Antheil sketched out the idea for the frequency-hopping system, which was to use a perforated paper tape which actuated pneumatic controls (as was already used in player pianos).

Antheil was introduced to Samuel Stuart Mackeown, a professor of radio-electrical engineering at Caltech, whom Lamarr then employed for a year to actually implement the idea. Lamarr hired the Los Angeles legal firm of Lyon & Lyon to search for prior knowledge, and to craft the application for the patent which was granted as U.S. Patent 2,292,387 on August 11, 1942, under her married name Hedy Kiesler Markey.
