Edwin Armstrong was an American inventor born in 1890 in New York City. He invented a large part of modern radio technology, including frequency modulation (FM) broadcasting. Armstrong married Marion McInnis, whom he gifted the world's first portable radio. Though honored for his inventions with medals, Armstrong's later years were marked by patent litigation and he ultimately died by suicide in 1954.
