Pre-naming · 1700s–1900
Autistic people existed.
Nobody had a word for it.
Before "autism" was named in 1908, autistic people lived — often invisible, sometimes celebrated as eccentric geniuses, frequently institutionalized as "feeble-minded." Folk traditions called them changelings, fairy-touched children. The medical profession barely noticed them. The eugenics movement (1920s–30s) noticed them only to harm them.
Victor of Aveyron — the Wild Boy (1797)
In 1797, a boy of perhaps 10 was found alone in the forests of southern France. He didn't speak, avoided social contact, was sensitive to sound and touch, fixated on objects in specific ways. Jean Marc Gaspard Itard, a young physician, took on his care and education for five years. Itard's case study became one of the first written records of what we'd today recognize as autistic traits — though Itard understood it as a "savage state" caused by isolation, not as a different neurology.
Henry Cavendish — the scientist (1731–1810)
Cavendish discovered hydrogen, calculated the density of Earth, and pioneered electrical experiments a century before they were rediscovered. He was also profoundly socially atypical — communicated mostly via written notes, avoided eye contact, lived a rigorously ordered life, ate the same meal daily. Modern biographers and the Royal Society itself have retrospectively recognized Cavendish as autistic. He was tolerated, even celebrated, because his work was undeniable.
The "changeling" tradition
Across British, Irish, Scandinavian, and German folk traditions, an autistic child was often understood as a "changeling" — a fairy child swapped for the family's "real" child at birth. Sometimes this framing was protective (the child was special, sent by the fairies). Often it was monstrous (the changeling was a trick, to be returned to the fairies through abandonment or worse). The tradition tells us autistic children were noticed; they were just explained through the wrong framework.
The asylum + eugenics decades (1850s–1930s)
By the late 19th century, autistic adults who survived childhood often landed in asylums — institutionalized as "idiots," "imbeciles," or "feeble-minded" under labels that combined autism with intellectual disability, severe mental illness, and physical disability. The American eugenics movement (1900–1940s) actively sterilized "defectives" by court order; tens of thousands of autistic people were among those whose reproductive rights were stripped without consent. The Nazi T4 program (1939–1945) systematically murdered an estimated 200,000 disabled people including many autistic children — a history Hans Asperger participated in via referrals (a fact obscured for decades after his death).
"The history of autism before the name 'autism' is the history of autistic people being misread, mislabeled, and frequently destroyed by systems that didn't have a category for them." — Steve Silberman, NeuroTribes (2015)
The pre-naming era ends with a paradox: autistic people existed for all of human history, but the modern framework for recognizing them — and protecting them — didn't arrive until the early 20th century. And the framework that did arrive turned out to be the worst possible kind.
