Jack Stewart, Canadian-American ice hockey player (b. 1917)
John Sherratt "Black Jack" Stewart (May 6, 1917 – May 25, 1983) was a Canadian professional ice hockey defenceman who played 12 National Hockey League (NHL) seasons for the Detroit Red Wings and Chicago Black Hawks. He won two Stanley Cup championships with the Red Wings and was named to the post-season NHL All-Star Team on five occasions: three times on the first team and twice on the second. Stewart also played in the first four NHL All-Star Games. After completing his NHL career as captain of the Black Hawks, he went on to coach numerous teams at various levels of hockey.
Stewart was regarded as the hardest hitting defenceman of his time, a reputation that earned him his nickname. His style of play routinely resulted in injuries and scars; he defied expectations by returning to the game after suffering a ruptured disc in his back and later a fractured skull. He was inducted into the Hockey Hall of Fame in 1964, and is also honoured by the Manitoba Hockey and Sports Halls of Fame.
