Lester Bowles "Mike" Pearson, PC, OM, CC, OBE (23 April 1897 - 27 December 1972) was a Canadian professor, historian, civil servant, statesman, diplomat, and politician, who won the Nobel Peace Prize 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 minority governments following elections in 1963 and 1965. During Pearson's time as Prime Minister, his minority government introduced universal health care, student loans, the Canada Pension Plan, the Order of Canada, and the current Canadian flag. During his tenure, Prime Minister Pearson also convened the Royal Commission on Bilingualism and Biculturalism. With these accomplishments, together with his ground-breaking work at the United Nations and in international diplomacy, Pearson is generally considered among the most influential Canadians of the 20th century.
