In October 1912 the Harriet Lane Home officially opened. It was the first children’s clinic in the United States that was associated with a medical school, being the Quaker Johns Hopkins School of Medicine. Eventually “treating” over 60,000 children a year, the Harriet Lane Home became a pioneer treatment, teaching, and research clinic. From 1930 to 1963 Helen Taussig, who helped to develop the blue baby operation, headed the pediatric cardiac clinic. Child psychiatrist Leo Kanner did studies of autistic children. Lawson Wilkins established an endocrine clinic that developed procedures used universally to treat children with certain glandular disorders, including dwarfism. John E. Bordley and William G. Hardy broke ground in detecting hearing impairments in very young children. Above all John Howland and Edwards A. Park, who directed the Home from 1927-1946, allowed the many specialty clinics to flourish and train pediatricians who became prominent throughout the country.
