Horace Joseph Gaul (December 21, 1883 – July 9, 1939) was a Canadian professional ice hockey and lacrosse player who played from 1904 until 1913 most notably with the Pittsburgh Professionals, Haileybury Comets, Ottawa Senators and Toronto Tecumsehs. As a lacrosse player he was a member of the Ottawa Capital Lacrosse Club.[2]
Born in Gaspé, Quebec, Canada, the Gaul family moved to Ottawa, Ontario. Horace first played senior amateur hockey for the Ottawa Silver Seven in 1904–05, a member of the Stanley Cup winning squad. In 1906, he became professional, joining Pittsburgh of the International Hockey League.[3] In 1907, he returned to Canada, playing for Brockville and Renfrew senior teams.
In 1908–09, Gaul split his time with Duquesne Athletic Club (of Pittsburgh) and Haileybury. He stayed with Haileybury for the inaugural National Hockey Association (NHA) 1910 season. When the team folded the next year, he returned to play for Ottawa and won a second Stanley Cup in 1911. In 1911, he joined New Glasgow of the Maritime Professional Hockey League (MPHL). He played his final season in 1912–13 for the new Toronto Tecumsehs of the NHA.
