Dates of existence



Paul E. Lacy was a professor emeritus of Washington University School of Medicine and a pioneer in the treatment of diabetes, having developed islet transplantation in the 1950s. He graduated from the Ohio State University with a B.S. in 1944 and a M.D. in 1948. Lacy completed graduate work in anatomy and experimental pathology at the Mayo Clinic and received a Ph.D. in the discipline from the University of Minnesota in 1955. In the same year, Washington University School of Medicine appointed him to be an assistant professor in the Department of Anatomy. It was during that time Lacy began his groundbreaking research of endocrine cells in the pancreas that led to the discovery and success of islet transplants as an experimental treatment for Type I diabetes mellitus throughout the 1970s and 1980s.

Due to his rising reputation for his research, Lacy was named the Edward Mallinckrodt Professor and chair of the Department of Pathology in 1961, which he held for 23 years until his retirement in 1984. Along with his work in medicine, Lacy was elected to the National Academy of Sciences and helped create the Juvenile Diabetes Research Foundation.
