The Rockefeller Archive Center is a repository of historical materials and a research center dedicated to the study of philanthropy and the many domains touched by American foundations, individual donors, and the civil society organizations they support. It was established in 1974 initially to gather, preserve, and make accessible the records of the Rockefeller family and their far-reaching philanthropic endeavors, such as the Rockefeller Foundation, and Rockefeller Brothers Fund. The Archive Center today holds the archives of major foundations, cultural organizations, research institutions, and many individuals associated with these organizations.
