from September 1960 through April 1963. As before, the character of Margaret was portrayed as a voice of reason, but Jim's character was softened to that of a thoughtful, yet Caspar Milquetoast-type father who offered sage advice in response to his children's problems. Jim was a salesman and manager of the General Insurance Company in Springfield, while Margaret was a housewife. Their home was located at 607 Maple Avenue. One history of the series characterized the Andersons as "truly an idealized family, the sort that viewers could relate to and emulate."
