Larson began his Hollywood career as a messenger at MGM studios, cashing paychecks for acting legends such as Lionel Barrymore and hunting down stars such as Judy Garland when they were late, The (Portland) Oregonian said Sunday. He later became a studio screenwriter, writing shorts for features that ran before films.
Larson was one of the original writers for Saturday morning fare as "The Lone Ranger" and "Sky King." During 1960s and 1970s, Larson was both a writer and producer of television shows such as "The Interns," "Cade's County" and "The F.B.I."
Larson, who died Thursday, also enjoyed a career as a novelist, writing mysteries, including a Crime Club series called "Muir's Blood" and "Matthew's Hand."
He is survived by his wife, Alice Larson.
