William Ronald Durnan (January 22, 1916 – October 31, 1972) was a Canadian professional ice hockey goaltender who played seven seasons with the Montreal Canadiens in the National Hockey League (NHL). During his career he was one of the most dominant goaltenders in the NHL, winning the Vezina Trophy for fewest goals allowed six times, being named First All-Star Team as best goaltender six times, and helped the Canadiens win the Stanley Cup two times. Dealing with a nervous condition throughout his career, Durnan retired in 1950, citing the stress of playing professional hockey. Durnan also served as the captain of the Canadiens in 1948, the last goaltender to be allowed to captain his team. In 1964 Durnan was inducted into the Hockey Hall of Fame, and in 2017 he was named one of the '100 Greatest NHL Players' in history.
