This large hospital was established by the Veterans Administration in 1924, in Tupper Lake, to help manage the many cases of tuberculosis among veterans of World War I. After the discovery of effective antibiotics in the late 1940s, the tuberculosis care centers around Saranac Lake slowly closed. In 1965 the hospital was taken over by the state’s Office for People with Developmental Disabilities. It is now the Sunmount Development Center, managed by a private company, supported by Medicare.
