In 1940, the Federal Communications Commission got its first demonstration of FM radio by Major Edwin H. Armstrong.
According to Major Armstrong’s niece, Jeanne Hammond:
Another inventor, Lee DeForest, challenged Armstrong’s priority for this discovery and the issue was twice argued before the US Supreme Court—which found in DeForest’s favor. However, the scientific community has always credited Armstrong for the invention and he received a gold medal for it from the Institute of Radio Engineers.
