In the 1970s, historians noted a schism in the health sciences. On one side were the "medical historians," doctors who combined enthusiasm and clinical expertise to interpret the development of their profession; on the other were the "historians of medicine, " trained primarily in historical scholarship and dedicated to the interpretation of medical treatments within a social context. An even-handed discussion of this tension, including remarks from several physician-historians, is given by Terra Ziporyn in "Historians Strive to Improve Perspective, Practice of Medicine" (Journal of the American Medical Association, CCLIV, 1985, 2713-2720).
