Memorial Statement for Professor Alvin F. Sellers, V.M.D., M.S. (1917-2008) who was Professor (1960) of Physiology and Head of the Department of Physiology at the Cornell University College of Veterinary Medicine. "At the time of his appointment, he was internationally recognized for his work on ruminant digestion and ion transport. He would soon attract talented new faculty members that became world leaders in research and graduate training in gastrointestinal physiology and in the emerging field of comparative gastroenterology." Professor Sellers "was a dedicated experimental physiologist but was equally committed to applying the sciences basic to medicine in teaching and in veterinary medical practice." The memorial statements contained herein were prepared by the Office of the Dean of the University Faculty of Cornell University to honor its faculty for their service to the university.
