However Thompson is best known for paying Pudge Heffelfinger $500 to play for Allegheny against their rivals, the Pittsburgh Athletic Club.

Heffelfinger for playing (cash) $500."  The ledger is currently on display at the Pro Football Hall of Fame in Canton, Ohio. Uniq plc (formerly Unigate plc) was a British food manufacturer.
