Joseph Philippe Pierre Yves Elliott Trudeau (October 18, 1919 – September 28, 2000) was the fifteenth Prime Minister of Canada from April 20, 1968 to June 4, 1979, and from March 3, 1980 to June 30, 1984.
Trudeau led Canada through some of its most tumultuous times and was often the centre of controversy. Known for his flamboyance, he sometimes wore sandals or a buckskin jacket in the House of Commons; dated celebrities; occasionally used obscenities to insult his opponents, and on May 7, 1977, did a pirouette behind the back of Queen Elizabeth II.
