Analysis of information sources in references of the Wikipedia article "Ben Johnson (actor)" in English language version.
The most famous foreman on the Chapman-Barnard spread was Ben Johnson, Sr., a world-champion rodeo roper, the hero of the Osage. Ben, Jr., his son, known as 'Son' Johnson, would also become a world-champion roper, and a movie star to boot.
Ben Jr. got into the film business when his father sold some livestock used in Howard Hughes's film The Outlaw and sent his son along to help manage the stock.
In addition, he sponsored the Ben Johnson Pro Celebrity Team Roping and Penning competition in Oklahoma City to benefit the Children's Medical Research Inc., and the Children's Hospital of Oklahoma.
