In 1920, Mildred and Robert Woods Bliss purchased a historic estate, The Oaks. The Blisses hired the landscape gardener Beatrix Farrand to revitalize the estate's neglected grounds. Over the course of thirty years, Mrs. Bliss worked closely with Farrand to design every aspect of the garden. The Blisses renamed the property Dumbarton Oaks in 1933, before gifting it and their Byzantine and Pre-Columbian art collection to Harvard University in 1940. Dumbarton Oaks now houses a museum, library, and research institute. In 2014, National Geographic named Dumbarton Oaks one of the top ten gardens in the world.
