Question: Question: When was the founder of the International Professional Hockey League born? Passage:Much as was the case of the concurrent development of professional gridiron football, the Pittsburgh, Pennsylvania metropolitan area was one of the first areas to promote a professional ice hockey team. The Western Pennsylvania Hockey League began hiring professional players in 1902 and acted as a pro–am league. This league joined with teams in Michigan and Ontario to form the International Professional Hockey League in 1904, with Houghton, Michigan dentist Jack Gibson its founder. While this league had folded by 1907, it was the start of professional hockey. The United States would continue to see professional hockey with teams from the PCHL, beginning with the Portland Rosebuds, followed by a Seattle-based franchise a year later. When the Boston Bruins joined the NHL in 1924, the United States was finally represented in the league. It would continue to grow in the NHL until a peak in the 2000s (decade), when 24 of the NHL's 30 teams were in the United States (the loss of the Atlanta Thrashers to Winnipeg in 2011 reduced this number to 23; it returned to 24 American teams when the Vegas Golden Knights joined in 2017). The NHL will reach a higher peak when the Seattle expansion franchise joins the league in 2021-22 as the 25th American team. There are several other pro leagues in the US as well; as of 2019 these include the AHL, ECHL, SPHL, and FPHL. The AHL and ECHL are official minor leagues to the NHL, with the ECHL subservient to the AHL; the FPHL and SPHL operate as low-level independents.
