Jacob Gill Gaudaur, Jr., OC (October 5, 1920 – December 4, 2007) was a Canadian Football League (CFL) player, executive, and commissioner. His 45-year career in Canadian football, including 16 years as the league's fourth commissioner (and its longest-serving commissioner), oversaw the start of the modern era of professional Canadian football. As an amateur artist, Gauduar made two important contributions, designing both the Hamilton Tiger-Cats "Leaping Tiger" logo, as well as an early version of the CFL logo.
