Karl Swenson was one of the busiest performers in the so-called golden days of network radio. Swenson played the leading role in the seriocomic daily serial Lorenzo Jones, and was also heard on Our Gal Sunday as Lord Henry, the heroine's "wealthy and titled Englishman" husband. He carried over his daytime-drama activities into television, playing Walter Manning in the 1954 video version of radio's Portia Faces Life. From 1958 onward, Swenson was seen in many small roles in a number of big films: Judgment of Nuremberg (1961), How the West Was Won (1962), and The Birds (1963). One of his more sizeable movie assignments was the voice of Merlin in the 1963 Disney animated feature The Sword in the Stone. One of his last roles was the recurring part of Mr. Hansen on TV's Little House on the Prairie. Karl Swenson was married to actress Joan Tompkins.
