In 2006 the Exxon Mobil Corporation awarded $1.2 million to the Dolph Briscoe Center to research and write the fifth volume of Exxon’s official corporate history titled Exxon: Transforming Energy, 1973-2005. The volume was written by Dr. Joseph Pratt, Cullen Professor of History and Management at the University of Houston and published by UT Press in 2013. The Briscoe Center houses the ExxonMobil Historical Collection detailing the long history of ExxonMobil and its predecessor, subsidiary, and affiliate companies around the world.
