Robert S. Shepard, director of development, will succeed retiring Duke senior vice president John J. Piva as Duke's chief alumni and development officer, effective July 1. Together, Piva and Shepard led the Campaign for Duke, which raised $2.36 billion between January 1, 1996, and December 31, 2003, the largest fund-raising campaign in Duke history and the fifth-largest in the history of American higher education.
