Princeton is losing some major campus figures this summer, including history professor Robert Darnton, while former Senate Majority Leader Bill Frist ’74 is among those joining the faculty in the fall.

Darnton, a faculty member since 1968, became director of the Harvard University Library July 1. Other tenured faculty departing the Univer-sity include Carol Armstrong, professor of art and archaeology and women and gender, who is moving to Yale; Ihor Lemischka, molecular biology, to Mount Sinai School of Medicine; Josiah Ober, classics, to Stanford; David Srolovitz, mechanical and aerospace engineering, to Yeshiva College; M. Christine Stansell ’71, history, to the University of Chicago; Bruce Western, sociology, to Harvard; and Wayne Wolf, electrical engineering, to the Georgia Institute of Technology.

Frist, appointed for 2007–08 as the Frederick H. Schultz Class of 1951 Professor of International Economic Policy, will teach a fall graduate course in the Woodrow Wilson School on health policy and an undergraduate course on a similar subject in the spring.

Seven tenured professors whose appointments were approved by University trustees in June are among those who will arrive in the fall. Joining the economics department, which graduated more seniors last month than any other department, are professors B. Douglas Bernheim, from Stanford; Pinelopi L. Goldberg, from Yale; and David S. Lee *99, from Berkeley.

V. Kofi Agawu, a music professor at Princeton from 1998 to 2006, will return to the University after a year at Harvard. Also among those appointed in June are religion professor Judith Weisenfeld *92, from Vassar; Julian E. Zelizer, professor of history and public affairs, from Boston University; and associate professor Yueh-Lin Loo *01, chemical engineering, from the University of Texas.
