В 1890 г. родился американский радиоизобретатель Эдвин Армстронг

A Columbia University graduate and then professor earned his place in encyclopedias – there he is referred to as an inventor of frequency modulation and of superheterodyne and super-regenerative radio sets. For those who find radio terms meaningless, let us say that Armstrong’s inventions are still used to broadcast sound in radio and TV. It was Armstrong who developed the FM-broadcasting system and built the first FM-radio station. This is enough to leave one’s trace in history.
