Lee Metcalf (1911-1978) served as U.S. Congressman from Montana from 1952 to 1961 and as U.S. Senator from 1961 until his death in 1978. The papers reflect Metcalf's wide range of interests, but especially reflect his involvement in public utilities regulation and protection of the natural environment. Over half of the collection consists of general correspondence (1951-1978) arranged alphabetically by subject and government agency. Name index card files of correspondents are available, one of which is organized alphabetically, another is arranged by location in Montana. Additionally in the collection are series for bills, printed materials, campaign materials, speeches and writings, voting records, and clippings. The Vic Reinemer Subgroup consists of general correspondence, outgoing correspondence, and subject files generated by Reinemer in his capacity as Metcalf's executive secretary and as staff director of the Senate Subcommittee on Banking, Management, and Expenditures.
