David A. Kessler, M.D., former dean of the medical school, returned to the Sterling Hall of Medicine in December for the unveiling of his official portrait by artist Richard Whitney. At a ceremony in the Historical Library, colleagues and Yale President Richard C. Levin lauded the achievements of Kessler’s tenure from 1997 to 2003, specifically the construction of the Anlyan Center for Medical Research and Education and the recruitment of 11 department chairs. Kessler said that although the portrait is of one person, many people contributed to his accomplishments as dean. “These things do not happen alone,” he said.
