In 1920, after a long and careful search, Mildred and Robert Woods Bliss found their ideal country house and garden within Washington, DC. They purchased a fifty-three-acre property, described as an old-fashioned house standing in rather neglected grounds, at the highest point of Georgetown. Within a year, the Blisses hired landscape gardener Beatrix Farrand to design the garden. Working in happy and close collaboration for almost thirty years, Mildred Bliss and Beatrix Farrand planned every garden detail, each terrace, bench, urn, and border. The upper sixteen acres were transferred to Harvard University in 1940 to establish a research institute for Byzantine studies, Pre-Columbian studies, and studies in the history of gardens and landscape architecture.
