Biographical Note

Michael Joseph Mansfield was born on March 16, 1903 in New York City to Irish immigrant parents, Patrick and Josephine Mansfield. After his mother died in 1906, Mansfield was sent to live with his great aunt and uncle in Great Falls, Montana. In 1917, he dropped out of school and lied about his age to enlist in the U.S. Navy during World War I. After his Navy discharge, Mansfield re-enlisted as a private with the U.S. Army from 1919 to 1920. From 1920 to 1922, he served as a U.S. Marine. During his time with the Marines, Mansfield was deployed to the Philippines and China, trips that established his lifelong interest in Asia.

After his miliary service, Mansfield returned to Butte, Montana, where he worked as a miner and mining engineer until 1930. He was admitted to Montana School of Mines in Butte by examination and studied there from 1927 to 1928. He married Maureen Hayes, a former Butte high school teacher. He then transferred to Montana State University in Missoula, where he completed his B.A. and M.A. From 1933 to 1943, he was Professor of Latin American and Far Eastern History at Montana State University.

Mansfield was elected to the U.S. House of Representatives in 1942 and served five terms as the representative from Montana's First District. In October 1951, he was appointed by President Harry Truman as a delegate to the United Nations, Sixth Session, in Paris. He was elected to the U.S. Senate in 1952 and re-elected in 1958, 1964 and 1970. In 1958, Mansfield again served as delegate when President Dwight Eisenhower appointed him to the 13th General Assembly of the United Nations. In November and December 1962, he undertook a foreign policy assignment to West Berlin and Southeast Asia for President John F. Kennedy. He took a similar assignment for President Richard Nixon in 1969. In 1972, he was invited by Premier Chou-En-Lai to visit the People's Republic of China after diplomatic relations between the U.S. and China were reestablished. He returned to China in December 1974 and September 1976 on subsequent official visits. Through all of this international work, he remained very close to the people and concerns of Montana, and was notorious for his close contact with citizens around the state.

Mansfield's responsibility and prestige steadily increased through his tenure in Congress. He became Assistant Majority Leader (Majority Whip) of the Senate in January 1957, and served in that capacity until 1961, when he was elected Majority Leader of the Senate. He held that position until he retired from the Senate in 1977. He served longer than any other Majority Leader in the history of the U.S. Senate.

President Jimmy Carter appointed Mansfield Ambassador to Japan in 1977, and he was reappointed under President Ronald Reagan. He held the position of ambassador until 1988. Mansfield later worked as a consultant to Goldman Sachs in Washington, D.C. Maureen Mansfield died on September 20, 2000, and Mike Mansfield died on October 5, 2001.

Custodial History

Most of the collection was in Mansfield's possession until time of transfer.

Acquisition Information

The bulk of this collection was received directly from Mansfield's Washington, DC, office in 1969 and the early 1970s, with the addition of the unofficial ambassadorial papers in 1982-1986. Mansfield also made additional gifts of audio tapes, books, art objects, and clippings in 1979, 1980, 1983, and 1988. Some additional materials were also received from USIA and USIS in 1987. Additional materials were donated by Mike Mansfield's daughter, Anne, in 2003, 2004, and 2010.

Processing Note

The Mansfield papers were originally processed and prepared for transfer to the archives by Mansfield's staff, with assistance and consultation with The University of Montana archivist Dale Johnson. Likewise, the ambassadorial portion was largely prepared by Mansfield's staff, and were received in the archives as a separate collection. Once the papers arrived at the archives, they remained largely in their original state. There was extensive documentation prepared for the collection of art objects.

In 1997, the Mansfield Foundation awarded the archives a grant to re-describe the collection and make information about it more readily available electronically. This grant served as a base for much future work on the papers. The House, Senate, and ambassadorial papers were combined to create one continuous collection; many series were combined; art, memorabilia, audio, film, and video were re-integrated into the collection; the series were sampled and surveyed; photographs were removed from acidic albums and listed individually; and the archives collected documentation on preservation problems in the collection. In 1998-99, the Foundation awarded the archives another grant to work on the photographs and augment other descriptions.

Portions of the papers remain unprocessed. In 2016, additional materials from later in Mansfield's life were arranged, described, and became Series XXXVII.

In 2022, additional miscellaneous documents related to Mansfield's time in the U.S. Senate were discovered at the archives and processed into the collection as Series XXXVIII. These documents had seemingly been mislabeled, but there is no record of their custodial or acquisition history. Series XXXIX was processed in 2023. These materials had previously been separated from the collection under unknown circumstances but were returned to the Archives in 2021.

From early 2022 through early 2023, Series XXXV was cataloged, photographed, and uploaded to ScholarWorks.

Separated Materials

Most audio materials, especially press interviews, were separated during original processing and now comprise Oral History Collection 22 at the K. Ross Toole Archives. A number of books and government publications were separated to the library's general and government documents collection during original processing.

Related Materials

Mansfield's official ambassadorial papers are with the records of the State Department in the National Archives.
