Joe Malone, one of the great forwards of the early 20th Century, scored seven goals for the Quebec Bulldogs on January 31st, 1920. The Bulldogs defeated the Toronto St. Pats 10-6. Malone's record has yet to be equaled.
Malone also recorded a six-goal game that same season, and had three five-goal games for the Montreal Canadiens in 1917-18.
Known as "Phantom Joe," Malone won two Stanley Cups with the Bulldogs in the pre-NHL era, and another with Montreal before retiring in 1924.
In the NHL's modern era, two players have come close to Malone's record by scoring six goals in a game.
Red Berenson of the St. Louis Blues did it in 1968, and Darryl Sittler of the Toronto Maple Leafs in 1976.
