Peter H. Arger, an emeritus professor of radiology in the Perelman School of Medicine, died on December 28, 2022. He was 89.

Dr. Arger received his MD from the University of Illinois in 1961. He joined the faculty of Penn’s School of Medicine in 1972 as an assistant professor of medicine, and was promoted to associate professor five years later. He was a beloved and innovative member of Penn’s faculty, contributing expertise to an experimental in vitro fertilization in 1983, two years after his promotion to full professor. “Peter H. Arger was an exceptional human being, a very caring radiologist and also a true gentleman and my mentor,” said his student, Beverly Coleman , a board-certified radiologist at CHOP. “I was his very first abdominal imaging fellow at the University of Pennsylvania.” “Peter was a standout in the world of clinical ultrasound and was a major reason for my coming to Penn,” said Steven Horii, an emeritus professor of radiology at PSOM. “But he was more than a mentor. When he discovered that my wife and I had a fondness for modern dance and ballet, he would always share stories about performances he had seen and recommendations (‘must see’) for live and recorded performances. Those conversations and his enthusiasm that went with them are favorite memories of mine.”

Dr. Arger retired and took emeritus status in 2000. In his retirement, he was an active member of the School of Medicine’s Association of Senior and Emeritus Faculty, chairing its committee on data collection in 2004. He was influential in his field, inspiring the Peter H. Arger, MD Excellence in Medical Student Education Award of the American Institute of Ultrasound in Medicine.

Dr. Arger is survived by his siblings, Anastasia and Euginia Arger; and by many nieces and nephews. A funeral was held on January 4. In lieu of flowers, contributions may be made to St. Luke Greek Orthodox Church, 35 N. Malin Road, Broomall, Pennsylvania 19008.
