Born in Staunton, Virginia, in 1873, Eugene Lindsay Opie studied at Johns Hopkins University, earning both his undergraduate degree and his M.D. as part of the medical school’s first graduating class in 1897. He went on to build a long career in academic medicine, with appointments at Johns Hopkins, the Rockefeller Institute, Washington University, and later the University of Pennsylvania.
Opie is especially remembered for research that connected changes in the pancreas with diabetes and for major studies of tuberculosis, including its causes, transmission, diagnosis, and immunization. He also worked on cancer and other infectious diseases, and his reputation grew from the breadth of his investigations as much as from any single discovery.
Over more than seventy years in medicine, he became one of the leading American pathologists of his era and served as president of the American Association of Immunologists. He died in 1971, leaving behind a body of work that linked laboratory pathology closely to practical questions in human disease.
