Jack McLean (January 31, 1923 – October 14, 2003) was a Canadianice hockey player who played for the Toronto Maple Leafs for three seasons, from 1942–43 until 1944–45. He is best known for scoring the game-winning goal at the 10:18 mark of the fourth overtime period against the Detroit Red Wings on March 23, 1943 - one of the longest games in Stanley Cupplayoffs history. Jack was part of the Toronto Maple Leafs' Stanley Cup championship in 1944–45.
He was a 19-year-old university student when he joined the Leafs in 1942, playing forward at a time when many regulars left to join the war effort. Interestingly, McLean did not practise with the Leafs, and with but a few exceptions, was allowed only to play games in Canada (at home in Toronto and in Montreal). Whereas many young men dreamed of playing in the NHL, Jack used his NHL career to provide a university degree in engineering, which became his career after retiring in 1945.
