Lester B. Pearson

Lester Bowles Pearson (23 April 1897 – 27 December 1972) was a Canadian politician, diplomat, and scholar who served as the 14th prime minister of Canada from 1963 to 1968. He also served as leader of the Liberal Party from 1958 to 1968 and as leader of the Official Opposition from 1958 to 1963. Born in Newtonbrook, Ontario (now part of Toronto), Pearson pursued a career in the Department of External Affairs and served as the Canadian ambassador to the United States from 1944 to 1946. He entered politics in 1948 as Secretary of State for External Affairs, serving in that position until 1957 under William Lyon Mackenzie King and Louis St. Laurent. Pearson was the seventh president of the United Nations General Assembly from 1952 to 1953. In 1953, he was a candidate to become the secretary-general of the United Nations, but was vetoed by the Soviet Union. In 1957, Pearson won the Nobel Peace Prize for proposing the United Nations Emergency Force to resolve the Suez Crisis, which brought him international recognition. After the Liberal Party was defeated in the 1957 federal election, Pearson won the leadership of the party the following year. Under Pearson, the Liberals were defeated by prime minister John Diefenbaker of the Progressive Conservative Party in the 1958 and 1962 federal elections. He challenged Diefenbaker for a third time in the 1963 federal election, and formed a minority government. Pearson led the Liberals to a second minority government in 1965. During Pearson's tenure as prime minister, his government introduced social and economic programs and legislation, including the Canada Student Loan Program, the Canada Pension Plan, the Canada Assistance Plan, the Canada Labour Code, and universal health care. He established royal commissions on bilingualism and biculturalism and the status of women, oversaw the adoption of the Maple Leaf flag following the Great Canadian flag debate, and unified the Canadian Armed Forces. In 1967, Pearson presided over the Canadian Centennial celebrations. In foreign policy, Pearson's government signed the Auto Pact with the United States and declined to send Canadian combat troops to the Vietnam War. Under his government, Canada became the first country to implement a points-based immigration system for immigrant selection. After five years in power, Pearson resigned as prime minister and retired from politics. Pearson's domestic policies and diplomatic work, including his role in resolving the Suez Crisis, have been subjects of historical assessments. He has placed highly in surveys ranking Canadian prime ministers.
