Edwin Armstrong Invented Sound For Radio And TV
#1
Edwin Armstrong saw radio’s huge potential when no one else did. In 1898, Guglielmo Marconi sent a message in code over a wireless telegraph, the first form of radio transmission, but he didn’t think voice would ever be broadcast.

In 1906, Canadian inventor Reginald Fessenden sent the faint sound of his voice and violin by radio. The next year, Lee de Forest invented the Audion, which made long-range reception and greater clarity possible using headphones.
