Establishment of American Board of Internal Medicine, with five representatives from the American College of Physicians and four from the AMA Section on the Practice of medicine; in 1941, allergy, cardiovascular diseases, gastroenterology, and tuberculosis (later pulmonary medicine) were incorporated into the board as subspecialties with their own certification (Stevens, 231-235). (In 1970-71, six more subspecialties – endocrinology and metabolism; hematology; infectious disease; nephrology; and rheumatology – were added). Last two homeopathic medical schools, New York Homeopathic Medical College and Flower Hospital and Hahnemann Medical College and Hospital of Philadelphia relinquish their homeopathic status and become regular medical schools (Haller, 292).
