This handsome, light-haired actor of Scandinavian heritage entered films in 1941 as a supporting player and second string lead. Nelson evolved into a dashing TV lead in the 50s and 60s and found his greatest success on the Broadway stage in a series of hit comedies and musicals. He proved adequate and good-humored in his often limited film roles, usually cast as the requisite male lead who provided support to his established leading ladies including Ginger Rogers in "The First Traveling Saleslady" (1956), Ann Sothern in "Undercover Maisie" (1947), Margaret O'Brien in "Tenth Avenue Angel"
