After serving four years in South Dakota, Kanner attained a fellowship position at the Henry Phipps Psychiatric Clinic at the Johns Hopkins Hospital in Baltimore, Maryland in 1928 after attracting the attention of Adolf Meyer, director of the psychiatric clinic. In 1930, with monetary support from the Macy and Rockefeller Foundations, Meyer and Edward A. Park were able to establish the Children's Psychiatry Service at the Harriet Lane Home at Johns Hopkins, which was the first child psychiatry clinic in the United States, and appointed Kanner to develop the program. Despite his inexperience in the fields of pediatric and child psychiatry, Kanner was able to teach himself pediatric psychiatry. In 1933, Meyer made Kanner an associate professor of psychiatry at the Johns Hopkins University. In 1935 the first edition of his textbook, "Child Psychiatry" was published. This was the first English language textbook for child psychiatry.
