Dumbarton Oaks is a Harvard University research institute, library, museum, and garden located in Washington, DC. The institution is the legacy of Robert and Mildred Bliss, collectors of art and patrons of learning in the humanities. The museum houses world-class collections of Byzantine and Pre-Columbian art, two areas of interest to the Blisses. A third revolves around the historic garden, which Mildred Bliss created in close collaboration with renowned landscape designer Beatrix Farrand. Since 1940, when the Blisses gifted the estate and collections to Harvard University, Dumbarton Oaks has supported research in Byzantine Studies. Later it embraced Pre-Columbian and Garden and Landscape Studies. The support takes the form of fellowships and other awards, scholarly conferences, publications, and digital initiatives. In recent years, Dumbarton Oaks has also developed educational programs focusing on its collections and garden.
