Edwin Armstrong

Edwin Howard Armstrong (December 18, 1890 – January 31, 1954) was an American electrical engineer and inventor. Armstrong was the inventor of frequency modulation (FM) radio.

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).[

Work and patent disputes
Many of Armstrong's inventions were ultimately claimed by others in patent lawsuits. In particular, the regenerative circuit, which Armstrong patented in 1914 as a "wireless receiving system," was subsequently patented by Lee De Forest in 1916; De Forest then sold the rights to his patent to AT&T. Between 1922 and 1934, Armstrong found himself embroiled in a patent war, between himself, RCA, and Westinghouse on one side, and De Forest and AT&T on the other. At the time, this action was the longest patent lawsuit ever litigated, at 12 years. Armstrong won the first round of the lawsuit, lost the second, and stalemated in a third. Before the Supreme Court of the United States, De Forest was granted the regeneration patent in what is today widely believed to be a misunderstanding of the technical facts by the Supreme Court
Death
Alone and depressed over the FM patent dispute, Armstrong, dressed in his coat and hat, jumped to his death from the thirteenth floor window of his New York City apartment on January 31, 1954. His suicide note to his wife said: "May God help you and have mercy on my soul".[11][12] His widow Marion, who had been Sarnoff's secretary before marrying Armstrong, renewed the patent fight against RCA and finally prevailed

Great effort, thank you.
I wish you would be a great scientist inshaAllh]
but not commit suicide!!!!!haaaa
