James A. Chapman

Chapman married Leta McFarlin (1889–1974) in 1908, and moved to Tulsa in 1912. They had a son, H. Allen Chapman (1919–1979), who was born in Colorado in 1919.^[3]

Chapman and his family used the resulting fortune to establish philanthropic trusts that fund charities in Oklahoma, Texas, and Arkansas. Funds are only distributed to the named beneficiaries of the trusts, which include institutions such as the University of Tulsa, Trinity University of San Antonio, Texas, John Brown University of Siloam Springs, Arkansas, and the Oklahoma Medical Research Foundation.^[4] According to Internal Revenue Service Form 990 filings found at GuideStar, these trusts have reported well over one billion dollars in assets in recent years.

At the time of his death, James Chapman's estate was assessed to be worth $120 million.^[2]

Chapman was also very fond of ranching and worked on the Chapman-Barnard Ranch in Osage County, Oklahoma, for many years. He had long maintained that ranching, rather than business, was his first love.^[2]

In 1968, he was inducted into the Hall of Great Westerners of the National Cowboy & Western Heritage Museum.^[5]
