"Four Corners and a Void": Idiocy and Childhood Disability in Nineteenth-Century America.

Over the second half of the nineteenth century, thousands of Americans were admitted to schools for so-called idiotic children, later known as institutions for the feebleminded and linked to the Eugenics movement. While idiocy is often presumed to be the antecedent of intellectual disability, an analysis of the stories of three hundred children admitted to one such institution over a forty-year period demonstrates an unexpected diversity of appearances, abilities, and behaviors. Within the walls of the institution, idiocy was composed of children whose perceived abilities deviated from the expectations of their social position. Families further shaped the diagnosis of idiocy by negotiating the timing of admission for their children, influenced not only by personal factors, but by shifting educational and employment opportunities, and cultural tolerance of diversity. Consequently, idiocy became the broadest descriptor of disability during the nineteenth century.
