Biography: In films from the mid-'60s, American actor Richard Bull was seen in The Satan Bug (1965), The Thomas Crown Affair (1968), Secret Life of an American Wife (1969), Newman's Law (1971), and several other major Hollywood productions. Many of these roles were bits or atmosphere characters: guards, policemen, and the like. Television afforded Bull larger character roles, especially in the sitcom field. Within a ten-year period (1964-1974), he guested on Gidget, Family Affair, Gomer Pyle, USMC, The Andy Griffith Show, My 3 Sons, Room 222, and Bewitched (as pilgrim John Alden in a "flashback" episode). He also had a recurring role as a ship's doctor on the mid-'60s fantasy weekly Voyage to the Bottom of the Sea. From 1974 through 1982, Richard Bull played store proprietor Nels Oleson, the even-tempered, long-suffering husband of overbearing Harriet Oleson on Little House on the Prairie. Bull continued to appear in films and episodes of TV shows until his death in 2014 at age 89.
