Kanner, Leo (1894–1981)Leo Kanner is a world-renowned psychiatrist who substantially influenced the field of child psychiatry by providing the first published, professional description of early infantile autism in 1943 (Neumarker,). Born in Austria, Kanner was college-educated in Germany, where he attended the School of Medicine at Fiedrich-Whilhelms-University of Berlin. His studies were interrupted with his service in the Austrian Army during World War I. After the war, he resumed his studies at the University of Berlin and obtained his MD in 1921 (Sanua,). Kanner worked as cardiologist in Germany, then, in 1924 he immigrated to the United States, where he became an assistant physician in the state hospital of Yankton, South Dakota. Three years later, he was invited by Professors Adolf Meyer and Edward A. Park to inaugurate the first psychiatry service in a pediatric hospital in the United States. In 1935, Kanner published Child Psychiatry, the first English language textbook on child psychiatry (Eisenberg,). From 1971 to 1972, Kanner was the Editor for the Journal of Autism and Childhood Schizophrenia, later renamed the Journal of Autism and Developmental Disorders. Two years before his retirement, Kanner became full professor of child psychiatry at Johns Hopkins University Hospital in Baltimore, Maryland and actively worked as a professor and psychiatrist in a private practice until shortly before his death in 1981, at the age of 86. By the time he died, Kanner had published 10 books and 300 articles.
