The sudden death of Professor GARDNER MAURICE RILEY on the twenty sixth of September is mourned by the University community at large and felt as a profound personal and professional loss by his colleagues in the Department of Obstetrics and Gynecology in the Medical School. He was in his fifty-fifth year.

Professor Riley began his career in endocrinology at the State University of Iowa under the eminent Dr. Emil Witschi, and gained further experience at the Beltsville Research Center of the U. S. Department of Agriculture. Coming to the University's Medical School in 1942, he established himself as a consistently creative laboratory scientist, a trusted clinical adviser, and a warmly esteemed member of his Department.

He was instrumental in devising the "silver stain" procedure for detecting uterine cancer. His most generally known published work was the authoritative text Gynecologic Endocrinology. At the Medical Center, he directed the Reuben Peterson Memorial Research Laboratory. He was also a consultant on human embryology and development to the National Institutes of Health, and an active participant in international congresses of endocrinologists. In 1959 Bard College fittingly honored him with a Doctor of Science degree.

The Regents of the University join his colleagues in lamenting the early death of this most able and devoted man. And to Mrs. Riley and his surviving relatives, they express their deepest sympathy.
