An aggressive defenceman known as "Ivan The Terrible," Irwin played 155 games with the Montreal Canadiens and New York Rangers in the 1950s. He was best known as a regular enforcer for 2 seasons on Broadway in 1953-54 and 1954-55. Apart from his NHL tenure he was rugged player and crowd favourite in the minors and the Quebec Senior League. Lacking speed and a good shot, Irwin made himself useful by playing his position well. His nickname originated from his poor offensive skills as much as his rugged approach to defence.

Born in Chicago, Irwin debuted with the Boston Olympics in 1947-48 when they played in the Quebec Senior and Eastern Leagues. It was with the QSHL's Sherbrooke Saints that Irwin first began to assert himself against opposing forwards and gain a local following.

After 3 years with the Cincinnati Mohawks of the AHL, he was sold to the Montreal Canadiens and played his first 4 NHL games in 1952-53, making his NHL debut on October 12, 1952 vs Boston Bruins at Boston Garden in a 1-1 tie. Irwin kept waiting for his chance to replace Butch Bouchard on the blueline, but the wily veteran kept improving with age. In the off-season, Montreal shipped Irwin to the Rangers for Pete Babando and Eddie Slowinski.

New York Ranger press agent Herb Goren dubbed Ivan Irwin as Ivan the Terrible. However it was never quite determined whether Goren was referring to his short temper and rugged style of play, or his lack of talent!

Irwin scored his 1st NHL goal vs Harry Lumley of Toronto Maple Leafs ar 10:45 of 2nd period on February 21, 1954 at Madison Square Garden in a 6-1 Rangers win.

Irwin spent 2 years as a regular for the Rangers, then spent the majority of his time in the AHL. He enjoyed 4 good seasons with the Providence Reds and Buffalo Bisons where he was an AHL second team all-star (1957) and 1st team selection (1958, 1959) before retiring in 1960.

Irwin played in 155 regular season NHL games, scoring 2 goals (1 GWG), 27 assists with 214 penalty minutes and 5 NHL playoff games with 0 points and 8 penalty minutes.
