1948: Opening in 1948, Willowbrook State School was the largest institution in the world for the treatment of people with developmental disabilities. The school was created in an attempt to segregate the mentally disabled from the rest of society. It was depicted as an ideal place for residents. Numerous photographs surfaced of staff seemingly helping “well-served” residents in newspapers and other publications. Residents were shown receiving therapy and engaging in activities when this was not the reality. (College of Staten Island)
