- 1799: French physician Jean-Marc Gaspard Itard reports on Victor, the "Wild Boy of Aveyron," a child with social withdrawal and language delays, traits that later align with autism.
- 1908: Swiss psychiatrist Eugen Bleuler coins the term "autism" (from the Greek "autos," meaning self) to describe social withdrawal in individuals with schizophrenia. This sets the stage for early misconceptions, linking autism to schizophrenia for decades.
- 1943: Leo Kanner, an Austrian-American psychiatrist, publishes Autistic Disturbances of Affective Contact, describing 11 children with distinct traits like social withdrawal, communication issues, and repetitive behaviors. He coins the term "early infantile autism" and believes it is a lifelong condition caused by an innate inability to form affective contact. Kanner also suggests a biological basis but notes that parenting styles could contribute, which lays the groundwork for later misguided theories around 'refrigerator moms'
- 1944: Austrian pediatrician Hans Asperger publishes a paper on children with behaviors similar to Kanner’s description but with stronger verbal abilities. Asperger describes the condition as "autistic psychopathy", later known as Asperger syndrome.
- 1947: Kanner notes that many autistic children have above-average memory and specific areas of talent, observing what would later be understood as savant syndrome.
1950s: Psychoanalytic Theories and Misunderstandings
- 1950s. Institutionalization is common for autistic children (and real life institutions don't look the high end resort-like setting shown in RainMan)
- 1950s: Bruno Bettelheim promotes the "refrigerator mother" theory, blaming emotionally distant mothers for causing autism. This theory, grounded in psychoanalysis, dominates for decades and contributes to a stigma around autism, despite later being debunked. In 1967, Bettelheim publishes The Empty Fortress, further expanding on his theory by comparing autistic children to prisoners in emotional isolation, a concept later widely discredited for its lack of scientific basis.
- 1956: Researcher Paul Eugen Bleuler, who first coined "autism" to describe withdrawal in schizophrenia, influences early confusion between autism and schizophrenia. Autism is often misdiagnosed as childhood schizophrenia, or emotional disturbance as there is little understanding of its distinct nature.
1960 - 70s: The Rise of Advocacy and Early Research Shifts
- 1964: Temple Grandin, who later becomes one of the most famous autistic advocates, is diagnosed with autism at age 16. Her later work will help shed light on sensory sensitivities in autism and emphasize the potential of autistic individuals.
- 1964: Psychologist Bernard Rimland, the father of an autistic child, publishes Infantile Autism, which challenges the refrigerator mother theory and argues for a biological cause of autism. Rimland's work is pivotal in shifting the focus toward neurological and genetic research.
- 1964: Civil Rights Bill Bypasses People with Disabilities. While the Act helps end discrimination against racial minority groups and women in the workplace, it does not make provision for people with disabilities. The difference is that when considering civil rights for disabilities you need not just a seat on the bus but a way to get into that bus.
- 1965: Rimland along with Ruth Sullivan found the Autism Society of America (ASA) one of the first national organizations in the US dedicated to autism advocacy, supporting families and promoting research.
- 1967: "Autism: The Invisible Wall", a television documentary in the UK, helps bring autism to public attention by focusing on the challenges and misunderstood nature of autistic individuals.
- 1967: ICD-8 (Eighth Revision). The International Classification of Diseases released by Word Health Organization includes childhood psychosis and other related terms, but autism itself is not yet a distinct diagnostic category. Autism is often conflated with schizophrenia or broader childhood psychotic disorders.
- 1974: Last of the Ugly Laws Repealed.
- 1975: The US passes the Education for All Handicapped Children Act (EAHCA), which mandates free public education for children with disabilities, including autism. This later evolves into the Individuals with Disabilities Education Act (IDEA) in 1990.
- 1977: Twin studies by Folstein and Rutter provide the first strong evidence for a genetic component to autism, marking a major shift away from psychoanalytic theories. This study reveals that autism has a higher concordance rate in identical twins than in fraternal twins.
- 1977: ICD-9 (Ninth Revision) introduces Infantile Autism under the category of pervasive developmental disorders (PDD). This marks the first time autism is officially recognized as a separate diagnostic entity in the ICD system. The criteria are still relatively broad, and autism is seen as a disorder affecting early childhood development.
1980s: Diagnostic Shifts and Broader Recognition
- 1980: The DSM-III officially recognizes autism as a distinct diagnosis, separate from childhood schizophrenia, under the term "Infantile Autism". This formalizes autism’s recognition within psychiatry.
- 1981: British psychiatrist Lorna Wing introduces the term Autism Spectrum Disorder (ASD), emphasizing the broad range of abilities and challenges in autistic individuals. She also popularizes Asperger syndrome in the English-speaking world.
- 1985: The diagnostic ratio of autism is estimated to be 4 to 5 in every 10,000 children. This reflects limited awareness and more restrictive diagnostic criteria.
- 1987: The DSM-III-R revises the criteria for autism, leading to increased diagnoses.
- 1987: Behavioral psychologist Ivar Lovaas publishes results of Applied Behavioral Analysis (ABA) in improving behaviors in some autistic children. ABA remains controversial today due to criticisms from the autistic community about its social validity and ethics of behavior modification and its use of aversives like shocks to achieve the higher success results. Shocks continue to be used in centers like the JRC (Judge Rotenberg Center) even today.
- 1988: The film Rain Man, starring Dustin Hoffman as an autistic savant, brings autism into the cultural spotlight, although it reinforces stereotypes of autism as tied to intellectual disability or savant syndrome.
1990s: Expanding the Spectrum and Advocacy Growth
- 1990: Americans with Disabilities Act signed into law by Pres George HW Bush.

- 1993: ICD-10 (Tenth Revision) significantly revises the classification of autism. Autism Spectrum Disorders (ASD) are grouped under Pervasive Developmental Disorders (PDD). Subtypes include Childhood Autism, Atypical Autism, Asperger’s Syndrome, Rett Syndrome, and Pervasive Developmental Disorder-Not Otherwise Specified (PDD-NOS). ICD-10’s structure allows for a more nuanced understanding of autism and its variations, with greater distinction between different developmental disorders.
- 1994: The DSM-IV expands the definition of autism to include Asperger syndrome and Pervasive Developmental Disorder-Not Otherwise Specified (PDD-NOS), marking a significant shift in recognizing autism as a spectrum. The diagnostic ratio rises to about 1 in 1,000 children.
- 1995: The Yale Child Study Center launches the Yale Early Social Cognition Program, pioneering research on autism's social cognition and brain development.
- 1997: Lorna Wing introduces the "triad of impairments": social interaction, communication, and flexibility of thought, which becomes a core diagnostic feature of autism. This framework helped shape diagnostic criteria and broadened the understanding of autism as a spectrum.
- 1997: The UN's Standard Rules on the Equalization of Opportunities for Persons with Disabilities (adopted in 1993) begins to include autism under broader disability rights frameworks, encouraging global awareness and inclusion
- 1998: A study by Andrew Wakefield links the MMR vaccine to autism leads to much controversy.

This marked the first formal effort by the US government to streamline and prioritize autism research across various agencies.
