Memorial Statement for Professor Hadley Carruthers Stephenson, D.V.M. (1893-1976) who was Emeritus Professor of Small Animal Medicine at the New York College of Veterinary Medicine. He also served as a consultant to the Cornell Research Laboratory for Diseases of Dogs (later named the Baker Institute for Animal Health). Colleagues dedicated a laboratory for the study of canine diseases in his name at that Institute in 1960. "This was in recognition of his twenty-one years of service to the development and maintenance of a cooperative relationship between the Cornell Research Laboratory for Diseases of Dogs and its collaborators and supporters." In addition to being a true friend of dogs, Dr. Stephenson was also recognized for his revolutionary teaching methods: question the past, innovate, experiment, and improve tomorrow. "As a result, he helped develop many new methods for the treatment of small animal disorders involving therapeutic drugs and vaccines." 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.
