Jimmy Thomson was a rugged defenseman and team leader who spent nearly 800 games in the NHL during the 40s and 50s. In addition to his feisty nature he was a fine passer who often helped his club's transition game by carrying the puck up ice efficiently.
The Winnipeg native was a junior standout in Toronto with the St. Michael's Majors for two years. He spent most of his first pro season in 1945-46 with the AHL's Pittsburgh Hornets before joining the Maple Leafs on a full time basis the next year.
In all, "Jeems" supplied toughness and leadership on the Toronto defense for eleven seasons. He was regarded as one of the league's toughest foes and placed on the NHL Second All-Star team in 1951 and 1952. He also participated in seven All-Star Games and was an integral part of Stanley Cup wins in 1947, 1948, 1949 and 1951. During the 1956-57 season he spent time as the Leaf's captain. Prior to the 1957-58 schedule, Thomson was traded to the Chicago Black Hawks for cash. The deal was a result of Thomson's involvement with Ted Lindsay's attempt to found a player's association. He suited up for 70 games in the Windy City and helped solidify the team's blueline before retiring at the end of the regular season. Thomson settled down in Toronto and operated a fuel business for several years.
