James Richard Thomson was a former professional hockey player who played thirteen professional seasons with the Toronto Maple Leafs and the Chicago Blackhawks. Thomson was captain of the Maple Leafs during the 1956-1957 season. Thomson is a four-time Stanley Cup champion, winning the championship with the Maple Leafs in 1947, 1948, 1949 and 1951.
Thomson was born in Winnipeg, Manitoba. He was signed to a minor league contract by the Toronto Maple Leafs and headed to Toronto at the age of 16 to play junior hockey with the St. Michael's Majors, a Maple Leafs affiliate in the Ontario Hockey Association. Thomson would win the Memorial Cup junior championship with the Majors in 1945. After two seasons with the Majors, Thomson spent most of the 1945–46 season with the Pittsburgh Hornets in the American Hockey League before joining the Maple Leafs on a full time basis the next year. He went on to win the Stanley Cup with Toronto in 1947, 1948, 1949 and 1951.
At the beginning of the 1956–57 season, Thomson was named team captain, succeeding veteran Sid Smith, who gave up the title after his offensive production plummeted during his one season as captain the previous year. Thomson's time with the captaincy would be brief, as it was handed back to former captain Ted Kennedy when he made a comeback after retiring at the end of the 1954–55 season. Thomson became one of the leaders of Ted Lindsay's attempt to have a players' union certified. Thomson was secretary-treasurer of the association and led the organization drive within the Maple Leafs, which resulted in every member of the team except Kennedy wanting to join the union. Thomson's unionizing activities didn't go over well with Leafs president Conn Smythe, who called him disloyal. He was sold to the Chicago Black Hawks after 12 years with the Leafs. Lindsay was also traded to Chicago at the same time. Thomson played one season in Chicago and retired in 1958 at age 31. He had started a coal and oil company while playing for the Maple Leafs, and went into the business full-time following his playing career. Throughout his career, Thomson earned two appointments to the NHL Second All-Star Team (1951, 1952), as well as seven appearances in the NHL All-Star Game. For his accomplishments during his career, Thomson was named as an honoured member of the Manitoba Hockey Hall of Fame.
