Arthur James Mosby was born in 1888. Mosby brought the first radio and television stations to Missoula, Montana. After receiving a license in 1930, he constructed a transmitter from a diagram and parts list in an amateur radio magazine. It worked, and KGVO took the air in 1931. In 1954, Mosby established KMSO-TV on Channel 13 in Missoula. Mosby also was instrumental in bringing the CBS Radio Network to Montana. Mosby sold his interests in radio and television in the late 1950s and early 1960s, and concentrated on real estate through Fairviews Development Corporation.
Mosby married Ruth G. Greenough, daughter of Thomas L. Greenough, and they had two daughters. Mosby died on November 26, 1970.
