The man who invented FM Radio, Edwin Armstrong (1890–1954), had bizarre habits and lived a life that ended tragically.

Edwin Howard Armstrong was born in New York City, New York, in 1890. He studied at Columbia University and later became a professor there. He invented the regenerative circuit while he was an undergraduate and patented it in 1914, the super-regenerative circuit (patented 1922), and the superheterodyne receiver (patented 1918).

Armstrong loved radio towers and was prone to climbing them. He once even climbed to the top of the 450-foot RCA radio tower on top of the RCA Building in New York City and stood on the very top - absolutely infuriating the head of RCA at the time, David Sarnoff.

Oddly, Armstrong also sent a duplicate copy to Sarnoff’s secretary, Marion MacInnis, and she wound up marrying him.

Armstrong – who invented FM in 1933, committed suicide in 1954 by walking out of a high-rise building's window and falling to his death.
