19453 Murdochorne           Discovered 1998 Mar. 28 by J. Broughton at Reedy Creek Observatory.
Though also known for their work with others, the English comedy writer-performers Richard Murdoch (b. 1907) and Kenneth Horne (1907-1969) teamed up for the zany 1940s-1950s radio series Much Binding in the Marsh, the goings on at a ramshackle RAF base bringing welcome comic relief in the austere post-war years.
