Dumbarton Oaks, formally the Dumbarton Oaks Research Library and Collection, is a historic estate in the Georgetown neighborhood of Washington, D.C. It was the residence and garden of wealthy U.S. diplomat Robert Woods Bliss and his wife Mildred Barnes Bliss. The estate was founded by the Bliss couple, who gave the property to Harvard University in 1940. The research institute that has emerged from this bequest is dedicated to supporting scholarship in the fields of Byzantine and Pre-Columbian studies, as well as garden design and landscape architecture through its research fellowships, meetings, exhibitions, and publications. It also opens its garden and museum collections to the public, and hosts public lectures and a concert series. Dumbarton Oaks is distinct from Dumbarton House, a Federal Style historic house museum also located in the Georgetown area.
