Mike Mansfield worked in the Butte copper mines as a young man, then studied and taught history at what is now the University of Montana.
In Congress
Montana voters elected him to the U.S. House in 1942 and to the Senate in 1952. In 1961 he became Senate majority leader and held the post until he retired in January 1977. It remains the longest tenure in that role. He was known for a low-key, consensus-building style during a period that included major civil-rights and Medicare legislation.
Ambassador to Japan
Presidents of both parties appointed him U.S. ambassador to Japan, where he served from 1977 to 1988. He died in 2001.
In Montana today
His name is on the Mansfield Library at the University of Montana and the Maureen and Mike Mansfield Center, which focuses on Asia and U.S.-Asia relations.
