MD Class of 1975

John A. Horneff ’71, ’75 MD, of Charlottesville, Va.; Mar. 24, from complications of metastatic colorectal cancer. He was a member of the “Charter Twelve” first graduating class of Brown medical students (see “Build Your Own MD,” Jan.-Mar. ’23). He completed residencies in anatomic pathology at the University of Chicago and in internal medicine at Northwestern University, and a fellowship in clinical oncology at the National Cancer Institute. Disillusioned by experiences with specific individuals and systems in academic medicine, he changed paths and pursued his other passion, photography. As an independent thinker and a creative photographer, he was drawn to seeing ideas and objects unconventionally. He particularly enjoyed finding obscure visual features and relationships in the natural and human-built worlds and creating new images based on, but not anchored to, conventional ways of seeing. He was an avid follower of current events, constantly connecting them to historical precedent to compare and contrast personalities and events in an effort to understand historical and political movements. He enjoyed playing chess. He is survived by his wife, Christine Peterson ’72.

Joseph A. DiLorenzo ’71, ’73 MMSc, ’75 MD, of Saunderstown, R.I.; Jan. 12. He opened his own internal medicine practice in Cranston and was affiliated with Our Lady of Fatima Hospital and Roger Williams Medical Center. He was an avid camper and enjoyed hiking and canoeing. He is survived by a sister and brother-in-law, and seven nieces and nephews.

William Graham ’72, ’75 MD, of Phoenix; Oct. 24. He was a graduate of Brown Medical School’s first class and became an infectious disease specialist, practicing in both West Virginia and Phoenix. In retirement he was labeled with the title Pickle Man at Madison Heights Elementary School and Litter Guy on Central Avenue’s Bridle Path, a hobby that resulted in a local artist painting him on his route. He also volunteered to read in the middle school English classes. He is survived by a daughter, a son, a grandson, and a brother. 

Mark J. Rosen ’72, ’75 MD, of Great Neck, N.Y.; July 3, 2019. His distinguished career in pulmonary and critical care medicine spanned more than four decades. His research and administrative accomplishments at New York City and Long Island hospitals were many. Over the course of his career he was director of critical care at Mount Sinai Hospital, director of pulmonary medicine and critical care at Beth Israel Hospital, and chief of pulmonary critical care and sleep medicine at North Shore University Hospital. During his tenure with the American College of Chest Physicians, he served as president, medical director, and director of global education and strategic development. He was the recipient of numerous awards. He played guitar and his bands played at parties and special events at Brown from 1968 to 1975. He is survived by his wife, Lenie; two daughters; and three grandchildren.

Reid Coleman ’72, ’75 MD, of Columbia, Md.; Dec. 2. He practiced internal medicine for more than 20 years in Providence.
