The Pioneers finished the season with a 30-1-1 record and were hailed as "the greatest hockey team to ever represent an American college or university."
1938
William Masterton (August 13, 1938 – January 15, 1968) was a Canadian American professional ice hockey centre who played in the National Hockey League (NHL) for the Minnesota North Stars in 1967–68.
1955
He averaged a goal per game and finished with 49 points in 22 games in 1955–56 as the Canadiens won the Turnbull Cup.
He added eight points in six games during the Memorial Cup playdowns, however St. Boniface failed to reach the national championship final.
Following a second season in which he recorded 53 points in 30 games, Masterton chose to attend the University of Denver where he was offered a scholarship to play with the Denver Pioneers hockey program.
1958
Masterton played three seasons in Denver between 1958 and 1961, appearing in a total of 89 games, scoring 66 goals and 196 points in that time.
At the time of his graduation, he was the Pioneers' all-time leading point scorer, a record he held for 25 years.
1959
Masterton led the WCHA in scoring in 1959–60 with 44 points in conference play, and led Denver to the 1960 NCAA national championship.
1960
A college standout with the Denver Pioneers, Masterton was a member of National Collegiate Athletic Association (NCAA) championship teams in 1960 and 1961, was twice an NCAA All-Star and was the most valuable player of the 1961 NCAA Division I Men's Ice Hockey Tournament.
He briefly played in the Montreal Canadiens organization before settling in Minnesota where he played senior hockey.
He was a two-time NCAA All-American and was twice named to the Western Collegiate Hockey Association (WCHA) All-Star team, earning both awards in 1960 and 1961.
Masterton served as team captain for 1960–61, and was named the most valuable player of the 1961 national championship as he led Denver to a second consecutive title.
1961
Turning to professional hockey after graduating with an engineering degree, Masterton signed a contract with the Montreal Canadiens in 1961.
Led by Jean Béliveau and Henri Richard, the Canadiens were extremely deep at center, so Masterton was assigned to the Hull-Ottawa Canadiens of the Eastern Professional Hockey League.
He had 31 goals and 65 points for Hull-Ottawa, placing him in the top ten in both categories.
1962
Masterton was promoted to the Cleveland Barons of the American Hockey League (AHL) for the 1962–63 season, where he led the team with 82 points.
He finished as the runner up to Doug Robinson for the Dudley "Red" Garrett Memorial Award as the AHL's top rookie.
Faced with little opportunity to make the Montreal roster, Masterton left the professional game to complete his master's degree at the University of Denver.
He settled in Minneapolis, Minnesota, where he took a job in contracts administration.
He joined the Honeywell Corporation where he worked on the Apollo program.
He and his wife Carol adopted two children, Scott and Sally.
1964
After taking a year off from hockey in 1964, Masterton regained his amateur status so that he could play senior hockey in the United States Hockey League.
He played two seasons with the St. Paul Steers between 1964 and 1966.
1966
Masterton became a naturalized American citizen, allowing him to join the United States National Team in 1966–67.
He served as captain on that team and was considered its most valuable player.
1967
The NHL's 1967 expansion offered an opportunity to play for the newly founded North Stars, for whom he scored the first goal in the franchise's history.
Masterton's death sparked a long-running debate in hockey about the merits of wearing helmets, as few NHL players did so at the time.
The NHL expanded in 1967, doubling from 6 teams to 12.
Among the new entries was the Minnesota North Stars.
The new team's coach and general manager, Wren Blair, had scouted Masterton while he played with the US Nationals and purchased his NHL playing rights from the Canadiens.
Masterton was the first player to sign with Minnesota, agreeing to a two-year contract.
He said prior to the start of the 1967–68 season that being able to play in Minnesota was key as he would have been unlikely to consider an offer with any other team.
At the age of 29, Masterton made his NHL debut in the North Stars' inaugural game, played October 11, 1967, against the St. Louis Blues.
In that game, a 2–2 tie, Masterton scored the first goal in Minnesota franchise history.
His wife Carol later recalled that it was a "dream come true" for her husband: "He always wanted a shot at the NHL, and expansion was a wonderful thing for him and guys like him."
1968
He is the only player in NHL history to die as a direct result of injuries suffered during a game, the result of massive head injuries suffered following a hit during a January 13, 1968 contest against the Oakland Seals.
In his memory, the NHL created the Bill Masterton Memorial Trophy which it has awarded since 1968 to a player who demonstrates perseverance and dedication to hockey.
The North Stars retired his jersey number 19, an honour that followed the franchise when it later relocated to Dallas, Texas.
A native of Winnipeg, Manitoba, Masterton played two seasons of junior hockey with the St. Boniface Canadiens in the Manitoba Junior Hockey League (MJHL).
1979
Despite several efforts to mandate their use, it was 11 years before the NHL made them compulsory for all new players beginning in the 1979–80 season.
