Early Life and Education
Leo Kanner was born as Haskel-Leib Kanner on June 13, 1894, in Klekotov, Austria-Hungary (present-day Ukraine), to a devout Jewish family. In 1913, he enrolled at the University of Berlin, but his studies were interrupted by the outbreak of World War I. He eventually obtained his doctorate in 1921.
Immigration to the United States and Medical Career
In 1924, Kanner immigrated to the United States and worked at a hospital in South Dakota. In 1930, he was recruited by Adolf Meyer and Edward Park to establish the first pediatric psychiatry service at Johns Hopkins Hospital in Baltimore. He became a professor of psychiatry in 1933.
Kanner's Contributions to Psychiatry
Description of Childhood AutismKanner's most significant contribution was his seminal article "Autistic Disturbances of Affective Contact," published in 1943. In this article, he coined the term "autism" to describe a constellation of symptoms observed in 11 children. He noted their extreme autism, obsessions, echolalia, stereotypies, and difficulty forming normal affective bonds with others.
Collaboration with Leon Eisenberg
In 1956, Kanner and Leon Eisenberg published a revised set of diagnostic criteria for infantile autism, titled "Early Infantile Autism 1943-1955." They proposed five main criteria, including lack of social contact, adherence to routine, and resistance to change.
Hans Asperger and Autism Spectrum Disorder
Contemporaneously with Kanner, Hans Asperger was also studying children with similar symptoms. He used the term "autistic psychopath" to describe these individuals. Asperger's work laid the groundwork for the later concept of autism spectrum disorder.
Legacy of Kanner's Work
In the current diagnostic manuals (DSM-5 and ICD-11 beta), childhood autism and Asperger syndrome have been removed as separate diagnoses. Instead, the broader term "autism spectrum disorder" is used to encompass a range of conditions characterized by social and communication difficulties. Kanner's pioneering work laid the foundation for the understanding and treatment of autism spectrum disorder today.
