Margaret Rockefeller Strong (June 11, 1897 - December 5, 1985) was an American heiress and prominent member of the Rockefeller family. She was the maternal granddaughter of John D. Rockefeller and his wife Laura Spelman Rockefeller.
She was the daughter of Elizabeth "Bessie" Rockefeller (1866–1906) and Dr. Charles Augustus Strong (1862–1940).[1] Her maternal grandfather was Standard Oil co-founder John D. Rockefeller (1839–1937).
Margaret saved a row of Neo-Federal townhouses on Park Avenue designed by McKim, Mead & White from destruction by purchasing the property and giving one of the townhouses to the Queen Sofía Spanish Institute in 1965. She then donated the corner townhouse to her cousin, David Rockefeller, who there founded the Center for Inter-American Relations, now the Americas Society. In December 1979, Margaret donated her father's estate, Villa Le Balze in Fiesole, Tuscany, Italy to Georgetown University which operates an overseas campus there.[2]
