  • Draft of June 11 2009
  • (center) Edmund S. Muskie served as a U.S. Senator from 1959 to 1980. During his 22 years in Congress, Muskie was a member on the Environment and Public Works Committee, the Foreign Relations Committee, and the Governmental Affairs Committee. In addition, he chaired the Senate Committee on the Budget, the Air and Water Pollution Subcommittee (later known as the Environmental Pollution Subcommittee), and the Intergovernmental Relations Subcommittee. He was active in writing new laws, including the early environmental protection legislation of 1963 and 1966, and sponsorship of numerous acts, including the Intergovernmental Relations Act (1959), the Model Cities Act (1966), the Clean Air Act (1970), the Clean Water Act (1972), and the Budget Reform Act (1974). Muskie’s legislative record is long, complex, and vitally important to understanding his historical contributions to environmentalism, budgetary reform, fiscal responsibility, and myriad other aspects of 20th century politics in the United States.
