The T. Grier Miller Professorship of Medicine in Gastroenterology

T. Grier Miller

The University’s first professorship in the field of gastroenterology was established in 1977 through the generosity of T. Grier Miller, MD (1886–1981) and with contributions from his friends, colleagues, and grateful patients.

Dr. Miller, a distinguished alumnus of the Perelman School of Medicine Class of 1911, received the University’s first fellowship in medicine and remained on staff until he became Professor Emeritus of Medicine in 1953. In 1928, Dr. Miller organized the Gastrointestinal Section in the Department of Medicine and developed the Miller-Abbott Tube, which revolutionized gastrointestinal diagnosis, treatment, and surgery. He served as President of the Board of Trustees of the Hospital of the University of Pennsylvania and was President of the American Gastroenterological Association in 1951.
