Guy Weadick, an American trick roper who participated in the Dominion Exhibition as part of the Miller Brothers 101 Ranch Real Wild West Show, returned to Calgary in 1912 in the hopes of establishing an event that more accurately represented the "wild west" than the shows he was a part of. He initially failed to sell civic leaders and the Calgary Industrial Exhibition on his plans, but with the assistance of local livestock agent H. C. McMullen, Weadick convinced businessmen Pat Burns, George Lane, A. J. McLean, and A. E. Cross to put up $100,000 to guarantee funding for the event. The Big Four, as they came to be known, viewed the project as a final celebration of their life as cattlemen. The city built a rodeo arena on the fairgrounds and over 100,000 people attended the six-day event in September 1912 to watch hundreds of cowboys from Western Canada, the United States, and Mexico compete for $20,000 in prizes. The event generated $120,000 in revenue and was hailed as a success.
