Founded in 1981 by Mayor Edward I. Koch and its charter Board Chair, Joan K. Davidson, the Gracie Mansion Conservancy is a private not-for-profit corporation established to preserve, maintain, enhance, and enliven Gracie Mansion – one of the oldest surviving wood structures in Manhattan and home to the sitting mayors of New York City and their families since 1942, when the La Guardias arrived as the first official residents.
