Ronald F. Dorfman (1923-2012), an Emeritus Professor of Pathology at the Stanford University School of Medicine, had significant input in advancing the study of diseases of hematopoietic cells and the lymph nodes, which included identifying a disease that has been named after him. Dr. Dorfman was one of the founders of the field of Hematopathology, and, with Dr. Costan Berard, founded the Society of Hematopathology in 1981, serving as its president from 1982 through 1984, and published a classification of non-Hodgkin lymphomas in 1974, which was a variant of the Rappaport classification.
