William Kenneth Russell Mallen - Born October 4, 1884 in Morrisburg, Ontario – Died April 23, 1930 in Morrisburg, Ontario was a Canadian professional ice Hockey right winger.

"Mallen is buried in historic Mount Pleasant Cemetery in Toronto, Ontario"

Mallen played his first senior Hockey with the Cornwall Hockey Club (Cornwall Kolts) in the Federal Amateur Hockey League / FAHL, before joining the Wanderer Hockey Club / Montreal Wanderers to finish the 1903-04 season, where he helped the Wanderers win the FAHl championship in 1904.

Mallen turned professional with the Calumet Miners of the International Professional Hockey League (IHL) to start the 1904-05 season. The IHL was the first professional Hockey league in the world. His first season, Mallen scored 38 goals in 24 games to establish a goal-scorer's reputation, and finished second in league goal scoring behind teammate Fred Strike. The Caumet Miners won the league championship with a record of 18 Wins, 5 Losses, 1 Tie. Mallen was selected to play in the IHL All-Star game in the rover position.

Mallen was a fast skater and good stick handler, but was often the target of physical abuse by the players of opposing teams. After enduring several injuries incurred from other players abuse, Mallen quit the Miners soon after the start of his second season to protest the violence of the game. “Realizing that he was one of the best and fastest men in the league, it has been the effort of some players to lay (Mallen) out,” reported the Daily Mining Gazette., Mallen did return to Calumet for one final season in 1906-07, playing with his brother Jim on the team, and played just 11 games. Mallen finished the season with the FAHL Morrisburg Athletics.

Mallen then joined the Toronto Professional Hockey Club / Toronto Professionals of the Ontario Professional Hockey League / OPHL to start the 1907-08 season, but after 3 games was lured over to the Eastern Canada Amateur Hockey Association / ECAHA to play for the Montreal Hockey Club / Montreal AAA, where he finished the season, scoring 10 goals for Montreal in the final 7 games, but Montreal finished last in the ECAHA.

The Pittsburgh Athletic Club team was revived in for the 1907-08 season, along with the Western Pennsylvania Hockey League, and Mallen joined the team to start the season. He was the leading scorer with 12 goals, but then he jumped to the Renfrew Creamery Kings of the FAHL to finish the season. With the addition of Mallen, the Creamery Kings would win the FAHL championship in 1909, with Mallen scoring 4 goals in the final 3 games.

Mallen then joined the CHA / NHA Ottawa Hockey Club / Ottawa Senators for the 1909-10 season. Mallen was mostly a spare on the team, playing in 1 regular season game, scoring 2 goals, and did get to play in a Stanley Cup challenge game on January 5, 1910 vs the Galt Professionals, who had Mallen's brother Jim on their team. Ottawa won 12 to 3, and neither Mallen brothers scored for their team. Ken Mallen was recognized with the Ottawa Hockey Club, January 1910 Stanley Cup Champions, engraved on the Stanley Cup as Ottawa 1910" and "OTTAWA vs GALT/OTTAWA vs EDMONTON"

Mallen again joined another team to start the 1910-11 season, this time, the NHA Quebec Hockey Club / Quebec Bulldogs. Unfortunately for Mallen, the Bulldogs, who took over the defunct Cobalt Silver Kings franchise, had a rough initiation, finishing dead last with four wins and 12 losses in a 16-game season. Mallen scored 13 goals in 12 games played.

Mallen did get his image on his only Hockey card while playing for Quebec, which was the No. 7, C55 Imperial Tobacco Hockey Card from 1911.

Mallen then moved out to Western Canada to play in the Pacific Coast Hockey Association / PCHA, where he played his first three seasons with the New Westminster Royals, helping the Royals win the 1st PCHA championship and the Patterson Cup in 1912.

Mallen also took part in a series of speed skating races designed to showcase the PCHA’s high-paid talent. Mallen won easily over Si Griffis and Cyclone Taylor, who had earned his nickname in recognition of his skating rushes. The triumph cemented Mallen’s reputation as the "fastest man on ice".

The Royals then moved to Portland, Oregon, USA due to poor attendance in New Westminster, and the availability of a larger arena in Portland.

Mallen was quickly signed by the Vancouver Hockey Club / Vancouver Millionaires to start the 1914-15 season, and scored 9 goals in 14 regular season games. Mallen also sat on the bench as a spare player during the 1915 Stanley Cup championship games vs the Ottawa Senators, which saw the Vancouver Hockey Club win in 3 straight games.

Mallen was again part of a Stanley Cup winning team, and Vancouver had engraved on a silver band below the bowl “VANCOUVER, B.C. / 1914-15 / DEFEATED OTTAWA / 3 STRAIGHT GAMES.” they also engraved inside the bowl of the Stanley Cup on the flutes - "Vancouver Hockey Club" and all the teams players except Mallen. The reason for the snub remains unknown. Perhaps he had already left the club by the time of the engraving and so was excluded. Perhaps his departure had not gone well. Perhaps it was inadvertent, a clerical mistake.

Mallen then played for the PCHA Victoria Aristocrats in 1915-16 where it was in the local newspaper, the Victoria Daily Times “Mallen is the speediest player,” and “He possesses a wicked shot, and should add considerable strength in the local attack.”

Mallen finished out his pro Hockey career with the PCHA Spokane Canaries in 1916-17, scoring 10 goals in 23 games.

After his retirement from professional Hockey, Mallen returned to Ontario, and he held the position of instructor of sports at the Ottawa Playgrounds, was a professional figure skater at London, Ont., and acted as coach of the Morrisburg Maroons and Cardinal St. Lawrence Hockey League teams

Ken Mallen was the son of James Mallen, and had 2 older brothers James Irwin "Jim" Mallen and Ray Mallen, who both also played professional Hockey.
