Published in the journal "Nervous Child", "Autistic Disturbances of Affective Contact" was one of the most cited papers on autism in the twentieth century. In his landmark paper, Kanner took the term "autism," which Eugen Bleuler previously attributed to the inward, introspective symptoms typical in adult schizophrenia patients, and labeled the eleven children in his study as having "infantile autism." However, rather than relating his observations to the qualities and symptoms seen in schizophrenic adults, Kanner classified his description of "autism" to be independent from the psychotic disorder, explaining how autism was not a precursor to schizophrenia, and that the symptoms of the former appeared evident and present at birth. A significant work, this paper on "Kanner Syndrome" formed the basis for later research conducted by Kanner and others on what later became known as childhood autism.
