An extract of an article by John Schneider
Henry C. and Cora B. Gates founded the Gates Radio & Supply Company in 1922 in the kitchen pantry of their apartment in Quincy, Ill., primarily to create a job for their son, Parker S. Gates, who was only 15 years old at the time. He began by selling crystal radios to friends and neighbors in the community
 Gates Radio & Supply Company soon became a serious enterprise, and Parker’s father quit his job to head the family business, which they moved into a second floor commercial space in downtown Quincy.
Two more moves to increasingly larger factory space took place in the 1930s. In the middle of that decade, Gates built one of the industry’s first audio consoles and introduced its first AM transmitter, the 250 Watt model 100A. Gates purchased a larger factory located on the Mississippi River in Quincy in 1945, and then in 1953 constructed an even larger building. By the 1950s, Gates Radio had become one of the country’s principal radio equipment suppliers and a major provider of audio consoles, turntables, AM, FM and shortwave radio transmitters and accessories. It also made its first forays into the new field of television at that time. In December 1957, Harris Intertype Corp., a lithography and typesetting conglomerate that was making its first venture into the field of electronics, acquired the company. Parker Gates stayed on as the president of the division, which gradually phased in the Harris name and is today known as Harris Broadcast Communications.
