Armand "Bep" Guidolin (December 9, 1925 – November 24, 2008) was a Canadian ice hockey player and coach. He is notable for being the youngest player in National Hockey League history. He was born in Thorold, Ontario. He and Eleanor, his wife of 62 years, had four children. His family moved to Timmins, Ontario.
Guidolin stood 5'8" at 175 lbs, and was a left-shooting left winger in the NHL. He later went on to a coaching career. He was nicknamed "Bep" because his mother spoke Italian and very little English. Armand was the baby of the family and his mother pronounced baby as "beppy". The nickname stuck and was shortened to "Bep". He is the cousin of fellow NHL player and coach Aldo Guidolin.
His quick rise to the NHL was a direct result of World War II. The Boston Bruins were in dire need of replacements to fill the roster holes created by so many players leaving for military service. In 1944, his eligibility for military service brought a one-year break from his NHL career.
Guidolin also played for the Detroit Red Wings and the Chicago Black Hawks. Armand was an ardent supporter of the formation of a players' union, which led to the early demise of his NHL career in 1952. He played for nine years in the minors, then retired to a coaching career.
Guidolin also coached the Timmins Northstars of the Northland Intermediate Hockey League which went on to the Hardy Cup Finals for the All Canadians.
He also coached a Junior C team for a short time out of Angus Ontario known as the Essa 80s at the end of his career.
