Knopf was widely regarded as a kind man who took the time to talk to everyone, on both a professional and personal level. He had a vast knowledge in the field of endocrinology, but recognized that there was always more to learn and was passionate about it.

He retired from active faculty status in 1996, and continued his work as professor emeritus for another 14 years before fully retiring in 2010. The Division of Metabolism, Endocrinology & Diabetes created the Ralph Knopf Fellowship to honor him and his outstanding teaching abilities and dedication.
