The Keeley Institute, known for its Keeley Cure or Gold Cure, was a commercial medical operation that offered treatment to alcoholics from 1879 to 1965. Though at one time there were more than 200 branches in the United States and Europe, the original institute was founded by Leslie Keeley in Dwight, Illinois, United States. The Keeley Institute's location in Dwight, Illinois, had a major influence on the development of Dwight as a village, though only a few indications of its significance remain in the village.
