Dumbarton Oaks is an historic estate in the Georgetown neighborhood of Washington, D.C. It was the residence and garden of Robert Woods Bliss (1875–1962) and his wife Mildred Barnes Bliss (1879–1969).
The Dumbarton Oaks Research Library and Collection was founded here 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, especially through its research fellowships, meetings, exhibitions, and publications.
Dumbarton Oaks also opens its garden and museum collections to the public, and hosts public lectures and a concert series.
