Abstract: Papers, mainly 1957-1980, of William Proxmire, Democratic Senator from Wisconsin (1957-1989), known for his liberal views on social issues, his fiscal conservatism, and the Golden Fleece awards with which he drew attention to wasteful government spending. Included are biographical materials and clippings, constituent correspondence, speeches, books and articles, sound and video recordings, newsletters and press releases, and federal agency case files. Files of staff members, the heart of the collection, document numerous issues of special concern to the Senator: the fairness doctrine; ratification of the international Genocide Treaty; Great Lakes harbors and shipping; and the SST, the B-1 bomber, and other military spending. General subject files concern numerous topics such as abortion, economic development in Wisconsin, opposition to the Senate leadership of Lyndon Baines Johnson, taxes, and energy. Also present are campaign files, schedules, voting records, and filmed campaign ads, televised “reports from Washington,” and other films.
