From 1930 to 1960, Rustin McIntosh, MD, was chief of pediatrics at Babies Hospital. Under his leadership, the hospital was one of the first in the country to develop programs in neonatal care, pediatric surgery, radiology, neurology, hematology-oncology, and psychiatry. As the director of pediatrics at the Columbia University College of Physicians and Surgeons, he assembled a department of noted pediatric subspecialists. These included Dorothy Hansine Andersen (pathology), Hattie Alexander (infectious disease), William Silverman (neonatology), John Caffey (radiology), and James Wolff (Hematology-Oncology).
