By the 1942–43 season, the league was reduced to six teams. Those six teams are now known, somewhat misleadingly, as the "Original Six." There was no more expansion or contraction until 1967. There was also change at the top; in February 1943, league President Frank Calder collapsed during a meeting, dying shortly after. After receiving assurances from the league the Brooklyn franchise he operated would resume play after the war, Red Dutton agreed to take over as president. When the other team owners reneged on this promise in 1946, Dutton resigned as league president. In 1946, with Dutton's recommendation, Clarence Campbell was named president of the NHL. Campbell remained until retirement in 1977. Campbell's tenure matched the league's stability. For the first 21 years of his presidency, the same six teams competed for the Stanley Cup; that period has been called the "golden age of hockey". The NHL featured increasingly intense rivalries coupled with rule innovations that opened up the game. World War II extensively ravaged the rosters of many teams; by the 1943–44 season teams battled each other for players. In need of a goaltender, the Bruins won a fight with the Canadiens over the services of Bert Gardiner. Meanwhile, the Rangers were forced to lend forward Phil Watson to the Canadiens in exchange for two players, as Watson was required in Montreal for a war job, and refused permission to play in New York. With only five returning players from the previous season, Rangers general manager Lester Patrick suggested suspension of his team's play for the duration of the war. Patrick was otherwise persuaded; however, the Rangers managed only six wins in a 50-game schedule, giving up 310 goals that year. The Rangers were so desperate for players that 42-year-old coach Frank Boucher made a brief comeback, recording four goals and ten assists in 15 games. That year the Canadiens dominated the league, finishing with a 38–5–7 record. Five losses remains a league record for the fewest in one season; the Canadiens did not lose a game on home ice. Their 1944 Stanley Cup victory was the team's first in 14 seasons. The Canadiens again dominated the 1944–45, finishing with a 38–8–4 record. They were defeated in the playoffs by the underdog Maple Leafs, who eventually won the Cup. NHL teams exclusively competed for the Stanley Cup following the 1926 demise of the Western Hockey League. Though rejected by Cup trustees for various reasons, in the intervening years other teams, and leagues, attempted to challenge for the Cup.
