Edwin Howard Armstrong
December 18, 1890 - February 1, 1954
Inventor of the regenerative feedback circuit, the superheterodyne and frequency modulation. He received his electrical engineering doctorate at Columbia University and was at one time the largest individual shareholder of the Radio Corporation of America. His 30 year patent battle with Lee DeForest over the regenerative circuit still ranks as the longest patent litigation in American history. He was also railroaded out of his rights to FM by his former friend David Sarnoff, Chairman of RCA. After Dr. Armstrong's suicide, his widow prevailed in a landmark suit against RCA.

Arthur A. Collins
September 9, 1907 - February 26, 1987
A boy inventor and radio wizzard, Mr. Collins founded the Collins Radio Company of Cedar Rapids, Iowa. He built his small transmitter company into one of the largest communications and avionics corporations in the world. His personal contributions to what he called "more perfect communications" are legendary. Collins Radio perfected modern single sideband communications and made what is generally agreed to be the finest line of amateur radio equipment. The Collins company also pioneered the field of aircraft electronic navigation with its Flight Director, on-board radar, HF and VHF communications and early computer applications. Mr. Collins held the amateur callsign W0CXX until his death in 1987. His callsign now belongs to the Collins Amateur Radio Club in Cedar Rapids.
