Endowed Professorships

The Maurice R. Hilleman Chair of Vaccinology

Established by the Merck Company Foundation, the Chair honors the legendary immunologist Maurice R. Hilleman, who developed more than 40 vaccines for some the world’s most significant diseases—measles, mumps, rubella and hepatitis A and B among them. His vaccines have virtually eradicated many childhood illnesses and saved millions of lives.

Maurice R. Hilleman, PhD, DSc (1919–2005) spent most of his career at Merck, retiring as Senior Vice President in 1984. As an adjunct faculty member in the Department of Pediatrics at the Perelman School of Medicine, he often collaborated with The Children’s Hospital of Philadelphia (CHOP) and Penn Medicine. The Hilleman Professorship is awarded to a physician-scientist making significant contributions to vaccinology who is on the faculty of the Department of Pediatrics of the Perelman School and based at CHOP. The chair is intended to accelerate the pace of vaccine research at the University of Pennsylvania.

Among his achievements, Dr. Hilleman developed vaccines for chickenpox, meningitis and pneumonia and made significant discoveries regarding the cold-producing adenoviruses and the cancer-causing virus SV40. He served on numerous national and international advisory boards and committees across the academic, governmental and private spheres.

Dr. Hilleman has been recognized with the National Medal of Science, the Sabin Gold Medal and Lifetime Achievement Awards and the Lasker Medical Research Award, the nation’s highest biomedical award. He was elected to the National Academy of Science and the National Academy of Medicine. In 1996, Dr. Hilleman received a special lifetime achievement award from the World Health Organization.
