There may still be a chance to hear four Nobel Peace Prize laureates at Wayne State University at 5 p.m. Friday. WSU is working to add seating to its General Lectures Auditorium to accommodate a larger audience for Shirin Ebadi, 2003; Jody Williams, 1997; Rigoberta Menchu Tum, 1992; and Betty Williams, 1976 (who will appear on videotape). More than 900 people have reserved seats for the free event.
