The Western Pennsylvania Professional Football Circuit was a loose association of American football clubs that operated beginning in 1890. Originally amateur, professionalism was introduced to the circuit when William Walter "Pudge" Heffelfinger became the first athlete to play football professionally, having been paid to play in 1892.
By 1904, the exodus of pro football talent to the "Ohio League" and the arrival of the NYPFL in 1908 diminished the region's level of play and the national professional champions were usually claimed by the teams from Ohio or New York.
I sincerely appreciate the research work, and the information being shared. It is important and interesting history.
