The school had a long-term connection with T. Boone Pickens, who was appointed to its board of regents in 1969. On March 21, 1973, Pickens resigned from the board in protest, but was reappointed in 1981 and became its chair in 1982. He continued to chair its board until its merger with the Texas A&M system in 1990. In 1987, he pledged a $1.5 million matching gift to endow its business school, which was named in his honor. On November 24, 2004, the school issued a press release stating that it planned to remove Pickens' name from the T. Boone Pickens College of Business after university officials came to believe he had not completed pledges he made to the university. In fact, Pickens had satisfied his pledge, but asked to have his name removed. On December 1, 2004, the then-President Russell C. Long acknowledged the error and agreed to remove Pickens' name. Subsequently, Pickens donated $165 million to Oklahoma State University-Stillwater. In 2007, Pickens endowed the Pickens Professorship of Business and in 2010, he endowed the Pickens Professorship of Management. In 2017, the business school was named the Paul and Virginia Engler College of Business in recognition of the largest gift ($80 million) received by the university in its history.
