Bill Siebens may have made his fortune in the oil industry, but his legacy will be in another iconic western Canadian symbol. In June 2012, Siebens made a donation to the Calgary Stampede Foundation worth more than $11 million, the largest gift in the Foundation’s history. The donation included an almost 8,000-acre portion of the OH Ranch, its historic buildings and the OH brand itself. The Ranch is already protected by the Nature Conservancy of Canada, and Siebens hopes that by donating it, the Stampede Foundation will use it to further promote and preserve western culture and values. “The Calgary Stampede has celebrated Alberta’s culture for the past 100 years, and this gift will encourage that for the next 100 years,” Siebens said at the time of the donation. It’s a fitting exclamation point on a successful career for the Canadian Petroleum Hall of Famer.
