Lester Bowles "Mike" Pearson, PC, OM, CC, OBE (April 23, 1897 – December 27, 1972) was a Canadian 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 also the 14th Prime Minister of Canada from April 22, 1963, until April 20, 1968, as the head of two back-to-back minority governments following elections in 1963 and 1965.
During his time as Prime Minister, Pearson's 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 groundbreaking work at the United Nations and in international diplomacy, Pearson is generally considered among the most influential Canadians of the 20th century.
