Origins & Early Life

Leo Kanner (; born Chaskel Leib Kanner, German: [ˈkanɐ]; June 13, 1894 – April 3, 1981) was an Austrian-American psychiatrist, physician, and social activist best known for his work related to infantile autism. Before working at the Henry Phipps Psychiatric Clinic at the Johns Hopkins Hospital, Kanner practiced as a physician in Germany and South Dakota. In 1943, Kanner published his landmark paper Autistic Disturbances of Affective Contact, describing 11 children who displayed "a powerful desire for aloneness" and "an obsessive insistence on persistent sameness." He named their condition "early infantile autism". Kanner was in charge of developing the first child psychiatry clinic in the United States and later served as the Chief of Child Psychiatry at the Johns Hopkins Hospital.
