Passage:Samuelson was born on a dairy farm in Ontario, Wisconsin, near LaCrosse. He considered becoming a Lutheran pastor before deciding on six months of radio school. His early work was based in Wisconsin, at WKLJ in Sparta, WHBY in Appleton, and WBAY-TV/AM in Green Bay. He is best known for his association with WGN Radio in Chicago, serving as the station's head agriculture broadcaster since 1960. In May of 1960, one of Mr. Samuelson's first assignments for WGN was to Emcee the National Barn Dance, a long running program that WGN had just acquired when WLS radio discontinued its association with Prairie Farmer Magazine.

He currently co-hosts (with associate Max Armstrong) the Morning Show on Saturdays. In addition, Samuelson hosts a three-minute daily "National Farm Report", and a weekly commentary, "Samuelson Sez"; both are syndicated to various stations across the country through Tribune Broadcasting's Tribune Radio Network.
