Lester Bowles "Mike" Pearson, PC, OM, CC, OBE was a Canadian professor, historian, civil servant, statesman, diplomat, and politician, who won the Nobel Prize for Peace in 1957 for organizing the United Nations Emergency Force to resolve the Suez Canal Crisis. He was the 14th Prime Minister of Canada from 22 April 1963 to 20 April 1968, as the head of two back-to-back Liberal minority governments following elections in 1963 and 1965.
During Pearson's time as Prime Minister, his Liberal minority governments introduced universal health care, student loans, the Canada Pension Plan, the Order of Canada, and the new Flag of Canada. Pearson also convened the Royal Commission on Bilingualism and Biculturalism, and he struggled to keep Canada out of the Vietnam War. In 1967, his government passed Bill C-168, which abolished capital punishment in Canada de facto - by restricting it to a few capital offenses for which it was never used, and which themselves were abolished in 1976. With these accomplishments, together with his groundbreaking work at the United Nations and in international diplomacy, Pearson is generally considered among the most influential Canadians of the 20th century.
