William Harrison was an American ice hockey coach. He was the head coach of Clarkson for a decade after World War II and provided the team with their only undefeated season.[1]
After graduating from Dartmouth in 1943 William Harrison signed up with the Marines at the height of the second world war.[2] Harrison left after three years of service and returned to Walpole, Massachusetts to coach at the local high school before accepting a position to become a professor of civil engineering at Clarkson and coach the ice hockey team.
Harrison Coached at Clarkson for 10 seasons, winning 3 league titles (after the Golden Knights founded the Tri-State League), making 2 Frozen Four appearances and providing Clarkson with an undefeated season in 1955–56 season.[3] Because the '56 team had eight seniors that were 4-year varsity players (they would have been ineligible to participate in the 1956 NCAA tournament) the team as a whole voted to decline the invitation to play.[2] Harrison received the 1956 Spencer Penrose Award despite the eligibility conflict and resigned as head coach two years later.
Harrison continued on in an academic capacity with Clarkson, receiving a fellowship from the National Science Foundation in 1959. He was inducted into Clarkson's Athletic Hall of Fame in 2008.[2]
