Duke family.

Duke Farms, a 2,700 acre estate located in Hillsborough, New Jersey, was developed by James Buchanan (J.B.) Duke beginning in 1893. After J.B. Duke's death in 1925, Doris Duke inherited the property. Over the course of nearly seven decades she worked to continue the legacy of Duke Farms and introduced environmentally-friendly and innovative farming methods into the operations of Duke Farms and purchased and restored farms and farmstead structures in order to forestall the rapid loss of farmland to urban development. When she died she left the majority of her estate to the Doris Duke Charitable Foundation with her expressed wish that Duke Farms be used to drive positive change on a number of key issues regarding the stewardship of the natural environment.
