Edwin Howard Armstrong (December 18, 1890^[2] – February 1, 1954^[3]) was an American electrical engineer and inventor, who developed FM (frequency modulation) radio and the superheterodyne receiver system.

He held 42 patents and received numerous awards, including the first Medal of Honor awarded by the Institute of Radio Engineers (now IEEE), the French Legion of Honor, the 1941 Franklin Medal and the 1942 Edison Medal. He achieved the rank of major in the U.S. Army Signal Corps during World War I and was often referred to as "Major Armstrong" during his career.^[4] He was inducted into the National Inventors Hall of Fame and included in the International Telecommunication Union's roster of great inventors. He was inducted into the Wireless Hall of Fame^[5] posthumously in 2001. Armstrong attended Columbia University, and served as a professor there for most of his life.
