As part of Thomas Edison National Historical Park, the Glenmont Estate is located within the historic residential community of Llewellyn Park, in the township of West Orange, New Jersey, approximately fifteen miles west of New York City. The 15.67-acre property (historic portion comprises 13.54 acres) reflects the history of the Thomas Edison family, as well as early community planning. The Glenmont grounds include the Edison home set within an open lawn dotted with a variety of native and exotic trees and shrubs, curving drives and walks, gardens, and a variety of service related buildings and structures. Thomas Edison acquired the Glenmont Estate in 1886 and resided there until his death in 1931. Mina Edison continued to live at the estate until her death in 1947. Originally interred in Rosedale Cemetery in nearby Orange, both Thomas and Mina were reinterred at the Glenmont Estate in 1963 at the request of their children. In 1955, the Glenmont Estate was designated the Edison Home National Historic Site and was acquired by the National Park Service in 1959, which began administering the site along with the Edison Laboratory National Monument, established in 1956. The home and laboratory were both redesignated as Edison National Historic Site in 1962, and later changed to Thomas Edison National Historical Park in 2009. The Glenmont Estate also contributes to the Llewellyn Park Historic District, listed in the National Register of Historic Places on February 26, 1986.
