Memorial Statement for Professor Raymond R. Birch, D.V.M., Ph.D. (1881-1959) who was Instructor (1910) of Pathology, Professor of Research, Head of the Veterinary Experiment Station, and Professor Emeritus at the New York State Veterinary College for nearly 40 years. "Hog cholera studies engaged most of his time from 1909 to 1921. Together with Dr. Milks, he initiated hog cholera serum and virus protection in New York. He conclusively proved that hog cholera is transmitted by uncooked pork trimmings." In 1921, Professor Birch "changed his major research from diseases of hogs to brucellosis of cattle" again applying sound research methodology to determine scientific evidence. He is also recognized for his teaching, publications, and the accomplishments of his graduate students. 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.
