Green Hills Farm, also known as the Pearl S. Buck House, is the sixty-acre homestead in Bucks County, Pennsylvania, where Nobel-prize-winning American author Pearl Buck lived for 40 years, raising her family, writing, pursuing humanitarian interests, and gardening. She purchased the house in 1933 and lived there until the late 1960s, when she moved to Danby, Vermont. She completed many works while on the farm, including This Proud Heart (1938), The Patriot (1939), Today and Forever (1941), and The Child Who Never Grew (1950).
