January 1, 2005 The Columbia University lab where Edwin Howard Armstrong developed FM radio technology in the 1930s has been given National Historic Landmark status. Armstrong's technology, which gave radio a clearer signal than the AM band, had its public debut in 1939, though FM wouldn't become widely popular for another three decades.
An electronics whiz, Armstrong conducted much of his radio research for military purposes - specifically, to enhance U.S. military communications in World Wars I and II. He had a frustrating time, however, with FM. He fought much of his life to keep the rights to his invention and finally committed suicide in 1951 when it seemed he had lost them. His wife kept battling and eventually prevailed in court. http://www.nydailynews.com/entertainment/ent_radio/story/267054p-228767c.html ---[Start Commercial]--------------------- World Radio TV Handbook 2005 is coming out.
