Michael Joseph Mansfield (March 16, 1903 – October 5, 2001) was an American politician and diplomat. A member of the Democratic Party, he served as a U.S. Representative (1943–1953) and a U.S. Senator (1953–1977) from Montana. He was the longest-serving Senate Majority Leader, serving from 1961 to 1977. During his tenure, he shepherded Great Society programs through the Senate, but strongly opposed the Vietnam War.
After retiring from the Senate, Mansfield served as U.S. Ambassador to Japan from 1977 to 1988, and upon retiring as ambassador, was awarded the nation's highest civilian honor, the Presidential Medal of Freedom (1989), in part for his role in the resignation of Republican President Richard Nixon. Mansfield is the longest serving American ambassador to Japan in history.
Early childhood 
Mansfield was born in the Brooklyn section of New York City to Patrick J. Mansfield and Josephine (née O'Brien) Mansfield, who were both Irish Catholic immigrants. His mother died from pneumonia in 1906, and his father subsequently sent Michael and his two sisters to live with an aunt and uncle in Great Falls, Montana. He attended local public schools, and worked in his relatives' grocery store. He turned into a habitual runaway, even living at a state orphanage in Twin Bridges for half a year.
Military service 
At 14, Mansfield dropped out of school and lied about his age in order to enlist in the U.S. Navy during World War I. He went on several overseas convoys on the USS Minneapolis, but was discharged by the Navy after his real age was discovered. He was the last known veteran of the war to die before reaching the age of 100. He then enlisted in the U.S. Army, serving as a private from 1919 to 1920.
Mansfield was a Private First Class in the U.S. Marine Corps from 1920 to 1922. He served in the Western Recruiting Division at San Francisco until January 1921, when he was transferred to the Marine Barracks at Puget Sound, Washington. The following month, he was detached to the Guard Company, Marine Barracks, Navy Yard, Mare Island, California. In April, he boarded the USAT Sherman, bound for the Philippines. After a brief stopover at the Marine Barracks at Cavite, he arrived at his duty station on May 5, 1921, the Marine Barracks, Naval Station, Olongapo, Philippine Islands. One year later, Mansfield was assigned to Company A, Marine Battery, Asiatic Fleet. A short tour of duty with the Asiatic Fleet took him along the coast of China, before he returned to Olongapo in late May 1922. His service with the Marines established a lifelong interest in Asia.
That August, Mansfield returned to Cavite in preparation for his return to the United States and eventual discharge. On November 9, 1922, Marine Private Michael J. Mansfield was released on the completion of his enlistment. He was awarded the Good Conduct Medal, his character being described as “excellent” during his two years as a Marine.
Following his return to Montana in 1922, Mansfield worked as a "mucker," shoveling ore and other waste, in the copper mines of Butte for eight years. Having never attended high school, he took entrance examinations to attend the Montana School of Mines (1927–1928), studying to become a mining engineer. He later met a local schoolteacher and his future wife, Maureen Hayes, who encouraged him to further his education. With her financial support, Mansfield studied at the University of Montana in Missoula, where he took both high school and college courses. He was also a member of Alpha Tau Omega fraternity. He earned his Bachelor of Arts degree in 1933, and was offered a graduate assistantship teaching two courses at the university; he also worked part-time in the registrar's office. He earned a Master of Arts degree from the Fletcher School of Law and Diplomacy in 1934 with a thesis entitled: "United States-Korean Diplomatic Relations: 1866-1910". From 1934 to 1942, he taught classes in Far Eastern and Latin American history, and also lectured some years on Greek and Roman history. He also attended the University of California at Los Angeles (1936–1937).
Congressional service 
In 1940, Mansfield ran an unsuccessful campaign for the Democratic nomination for the U.S. House of Representatives in Montana's 1st congressional district. However, he ran for the same seat in 1942 and won, handily defeating Republican businessman Howard K. Hazelbaker. He succeeded Jeannette Rankin, the first woman elected to the Congress, who had decided not to seek re-election.
Mansfield served five terms in the House, being re-elected in 1944, 1946, 1948, and 1950. His military service and academic experience landed him a seat on the House Foreign Affairs Committee. He went to China on a special mission for President Franklin D. Roosevelt in 1944, and served as a delegate to the ninth Inter-American Conference in Colombia in 1948. In 1951, he was appointed by President Harry S. Truman as a delegate to the United Nations sixth session in Paris. During his House tenure, he also expressed his support for price controls, a higher minimum wage, the Marshall Plan, and aid to Turkey and Greece; he opposed the House Un-American Activities Committee, the Taft–Hartley Act, and the Twenty-second Amendment.
In 1952, Mansfield was elected to the U.S. Senate after narrowly defeating Republican incumbent Zales Ecton. He served as Senate Majority Whip under Majority Leader Lyndon B. Johnson from 1957 to 1961. In 1961, after Johnson resigned from the Senate to become Vice President, Mansfield was unanimously elected the Democratic floor leader and thus Senate Majority Leader. Serving sixteen years, from 1961 until his retirement in 1977, Mansfield is the longest-serving Majority Leader in the history of the Senate. The Washington Post compared Mansfield's behavior as Majority Leader to Johnson's by saying, "Instead of Johnson's browbeating tactics, Mansfield led by setting an example of humility and accommodation."
An early supporter of Ngo Dinh Diem, Mansfield had a change of heart on the Vietnam issue after a visit to Vietnam in 1962. He reported to President Kennedy on December 2, 1962, that US money given to Diem's government was being squandered and that the US should avoid further involvement in Vietnam. He was thus the first American official to comment adversely on the war's progress.
As the President of the Senate, Mansfield delivered the lead eulogy on November 24, 1963, witnessed by Jacqueline Kennedy, as President Kennedy's casket lay in state in the Capitol rotunda: "And so she took a ring from her finger and placed it in his hands, and kissed him, and closed the lid of a coffin. A piece of each of us died at that moment."
During the Johnson presidency, Mansfield became a frequent and vocal critic of US involvement in the Vietnam War. In February 1965 he lobbied against escalating aerial bombardment of North Vietnam in the aftermath of Pleiku, arguing in a letter to the president that Operation Rolling Thunder would lead to a need for "vastly strengthened . . . American forces."
In 1964, Mansfield, as Senate Majority Leader, filed a procedural motion to have the proposed Civil Rights Act discussed by the whole Senate rather than by the Judiciary Committee, the latter having killed similar legislation seven years prior.
- honor all U.S. treaty commitments against those who might invade the lands of allies of the United States;
- provide a nuclear umbrella against threats of other nuclear powers;
- supply weapons and technical assistance to countries where warranted but without committing American forces to local conflicts.
In turn Nixon turned to Mansfield for advice and as his liaison with the Senate on Vietnam. Nixon began a steady withdrawal of U.S. troops shortly after taking office in January 1969, a policy supported by Mansfield. During his first term, Nixon reduced American forces by 95%, leaving only 24,200 in late 1972; the last ones left in March 1973.
During the economic crisis of 1971, Mansfield was not afraid to reach across the aisle to help the economy. He said:
"What we're in is not a Republican recession or a Democratic recession; both parties had much to do with bringing us where we are today. But we're facing a national situation which calls for the best which all of us can produce, because we know the results will be something which we will regret."
Two controversial amendments by Mansfield limiting military funding of research were passed by Congress.
- The Mansfield Amendment of 1969, "passed as part of the fiscal year 1970 Military Authorization Act (Public Law 91-121) prohibited military funding of research that lacked a direct or apparent relationship to specific military function. Through subsequent modification the Mansfield amendment moved the Department of Defense toward the support of more short-term applied research in universities." This amendment affected the Military Services, for example research funding by the Office of Naval Research (ONR).
- The Mansfield Amendment of 1973 expressly limited appropriations for defense research through ARPA, which is largely independent of the Military Services, to projects with direct military application.
An earlier Mansfield Amendment, offered in 1971, called for the number of U.S. troops stationed in Europe to be halved. On May 19, 1971, however, the Senate defeated this amendment by a vote of 61–36.
As Senator, Mansfield sponsored S.J.RES.25 : The joint resolution to authorize and request the President to issue a proclamation designating the fourth Sunday in September, 1973, as "National Next Door Neighbor Day", and in 1974 drafted legislation (S.J.RES.235) to honor the fourth Sunday in September of every subsequent year as "Good Neighbor Day".
U.S. Ambassador to Japan 
Mansfield retired from the Senate in 1976, and was appointed Ambassador to Japan in April 1977 by Jimmy Carter, a role he retained during the Reagan administration until 1988. While serving in Japan, Mansfield was highly respected. Mansfield is particularly renowned for describing the United States-Japan relationship as the 'most important bilateral relationship in the world, bar none'. Mansfield's successor in Japan, Michael Armacost, noted in his memoirs that, for Mansfield, the phrase was a 'mantra.' While in office, Mansfield also fostered relations between his home state of Montana and Japan. The sister city of Helena, capital of the state, is Kumamoto city, on the island of Kyushu.
The Maureen and Mike Mansfield Library at the University of Montana, Missoula is named after him and his wife Maureen, as was his request when informed of the honor. The library also contains the Maureen and Mike Mansfield Center, which is dedicated to Asian studies, and, like the Maureen and Mike Mansfield Foundation, "advancing understanding and co-operation in U.S.-Asia relations." The Mike Mansfield Federal Building and United States Courthouse in Missoula was renamed in his honor in 2002.
The Montana Democratic Party holds an annual Mansfield-Metcalf Dinner named partially in his honor.
Mansfield retired in 1989. In that year he received the Presidential Medal of Freedom. He received the United States Military Academy's Sylvanus Thayer Award. In 1990, Japan conferred on Ambassador Mansfield the Grand Cordon of the Order of the Rising Sun with Paulownia Flowers. This is Japan's highest honor for someone who is not a head of state.
- 1989 – Presidential Medal of Freedom.
- 1990 – United States Military Academy, Sylvanus Thayer Award.
- 1990 – Order of the Rising Sun with Paulownia Flowers, Grand Cordon (Japan).
Burial at Arlington 
|“||This gentleman went from snuffy to national and international prominence. And when he died in 2001, he was rightly buried in Arlington. If you want to visit his grave, don't look for him near the "Kennedy Eternal Flame", where so many politicians are laid to rest. Look for a small, common marker shared by the majority of our heroes. Look for the marker that says "Michael J. Mansfield, PVT. U.S. Marine Corps".||”|
