Duke University trustee David Rubenstein has donated $5.75 million to Duke's Sanford School of Public Policy to help the school meet a $40 million fundraising target in time for its inauguration, Duke President Richard Brodhead announced Tuesday.

Rubenstein’s gift will provide a $3.5 million endowment to support the school’s Program in Environmental and Energy Policy, $1.125 million to fund a distinguished speakers series and $1.125 million to provide internship support for public policy master’s degree students.

“David Rubenstein has been the greatest single supporter of the Sanford School, and it’s right that he should be the one to put us across the goal line,” Brodhead said in a statement. “I am deeply grateful for his wisdom as a trustee and his leadership in this historic development. Duke’s newest school will be a source of trained intelligence on the major issues facing this country and the world.”
