Sound innovation for WWII (player piano) (1 Jan 1940 Jahr – 1 Jan 1945 Jahr)

Beschreibung:

There is a need for secure radio trasmission because of the war effort. Hedy Lamarr and a sound innovator combine efforts to create a player piano which can play by itself. The technology is then applied to missiles so that missile transmissions can't be intercepted. This innovation is dismissed by the military however.
