Memorial Statement for Professor Thomas Richard Houpt, V.M.D., M.S., Ph.D. (1925-2003) who was appointed Professor (1971) of Veterinary Physiology at the Cornell University College of Veterinary Medicine where he was a central figure in the teaching of veterinary physiology to professional graduate and undergraduate students for 32 years. In the area of gastrointestinal physiology, Professor Houpt's "research turned toward behavioral physiology and, particularly, ingestive behavior--neural and hormonal factors regulating hunger, thirst and satiety using pigs as his experimental model." Often with his wife and collaborator, Katherine Albro Houpt, he "published extensively concerning the use of pigs as experimental subjects." 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.
