The Charles W. Durham and Margre Henningson Durham Center for Computation and Communication opened in 1989. The Durhams were 1939 graduates of Iowa State whose $3 million contribution to expand computer facilities at ISU led to the construction of the center. It houses the High Performance Computing facility that supports large-scale computing needs for scientific and instructional endeavors at the university. (Charles W. Durham was initiated into Tau Beta Pi by Iowa Alpha as an Eminent Engineer on April 20, 1986)
