A Patent Issued 72 Years Ago Today, Made Wireless Communications Possible

August 11, 1942 – Austrian actress Hedy Lamarr and George Antheil are issued a patent for their “Secret Communications System”.

George Antheil, an Avant-garde US composer, and neighbor of Hedy, used a technique to control several player pianos from a single player piano roll. The system used the player piano roll to randomly generate the transmission frequencies to control various devices; in this case, radio controlled torpedoes.

The invention was originally rejected by the Navy because it was thought the device was too bulky to be installed in torpedoes; however, an updated version of the device started showing up on Naval ships, three years after the patent expired, and was used during the Cuban Missile Crisis.
