In the 1930s, about 2% of San Francisco's children were diagnosed as intellectually disabled and placed in special education or institutionalized. Most of the children were of Italian descent. Teachers, physicians, psychologists and social workers authorized their placement in San Francisco's special education classes, specified the training that the children were to receive, and on occasion, referred children to Sonoma State Hospital for institutionalization. As professionals, they followed State mandates for compulsory education and were influenced by the prevailing philosophies of the time -- eugenics and social Darwinism. Pupils who fell behind in school were sent to a psychologist for individual testing; the child's 1916 Simon-Binet IQ test score was an important part of the diagnosis. The school psychologist, Olga Bridgeman and the head of special education, Louise Lombard had been trained to use the IQ test by Henry Goddard of Vineland School. The Sonoma State Hospital was headed by Fred Butler who took great pride in his sterilization program. A question asked in 1964 was where did they all go as adults? They were no longer considered intellectually disabled. A follow up study in 1984 partially answers that question.
