Psychiatric
Approximately 1400s CE — European changeling folklore and ecclesiastical records describing children with unusual behaviors
Autism was formally named and described only in the twentieth century, though historians have retrospectively identified accounts in earlier medical and social records that may have described individuals with similar characteristics. For most of recorded history, the behaviors and developmental patterns now associated with autism were interpreted through frameworks ranging from demonic possession and moral deficiency to genius, feeblemindedness, and childhood psychosis. The emergence of autism as a distinct diagnostic category reshaped psychiatry and generated decades of shifting theoretical explanations for its origins.
Historical Narrative
Before the twentieth century, no unified medical concept existed to describe the constellation of characteristics now associated with autism, and individuals who displayed unusual social behavior, limited speech, or intense focused interests were categorized according to whatever explanatory frameworks their era provided. Medieval European records described children who failed to speak, showed no interest in social interaction, and engaged in repetitive behaviors; these children were sometimes identified as changelings in folk tradition, creatures believed to have been substituted for human infants by supernatural forces. This belief occasionally had dangerous consequences, as families and communities sought to drive out or expose the supposed supernatural being.
During the early modern period, as European institutions began establishing facilities for those deemed mentally deficient or mad, individuals who today might be identified as autistic were housed alongside people with epilepsy, intellectual disabilities, and severe psychiatric conditions under the broad and imprecise category of idiocy or lunacy. Physicians of the eighteenth century began to distinguish among different types of mental deviation, and the French physician Jean-Marc Gaspard Itard gained particular historical attention for his work with Victor of Aveyron, a child discovered living wild in the forests of southern France around 1800. Itard attempted to educate Victor through systematic sensory training, and while his goals centered on civilization and language acquisition, his detailed observations of the boy's behavior and learning patterns attracted lasting scholarly interest.
The nineteenth century brought increasingly systematic classification efforts within the emerging fields of psychiatry and neurology. Édouard Séguin, a French physician who later worked in the United States, developed educational methodologies for children categorized as idiots and described subgroups within that population whose characteristics overlapped with what would later be defined as autism. Henry Maudsley, the influential British psychiatrist, wrote in the late nineteenth century about a form of childhood insanity affecting very young children, acknowledging that mental illness could originate in the earliest years of life rather than emerging only in adulthood.
The formal concept of autism emerged in the early 1940s through the nearly simultaneous but independent work of two physicians working on opposite sides of the Atlantic. Leo Kanner, an Austrian-born psychiatrist working at Johns Hopkins University in the United States, published a landmark 1943 paper describing eleven children who shared a distinctive pattern of profound social withdrawal, insistence on sameness, and unusual language development. Kanner used the term early infantile autism, drawing the word autism from the earlier psychiatric vocabulary of Eugen Bleuler, who had used it to describe the self-directed inner world of patients with schizophrenia. Almost simultaneously, Hans Asperger, a Viennese pediatrician, described a group of children with similar social and communicative differences but generally intact language development, in a paper that remained largely unknown outside German-speaking countries for decades.
In the years following Kanner's publication, psychoanalytic theories dominated American and European psychiatric thinking about autism's origins. Bruno Bettelheim popularized the deeply damaging refrigerator mother hypothesis, which attributed autism to cold, emotionally withholding maternal behavior, causing immense suffering among families. This theory was challenged and ultimately discredited through the work of researchers including Bernard Rimland, a psychologist whose own son was autistic, who argued in the 1960s that autism was neurological rather than psychogenic in origin. The gradual shift away from psychoanalytic etiological theories toward biological and developmental frameworks reshaped research programs and professional understanding through the latter decades of the twentieth century.
