The Rockefeller Foundation series consists of Rusk's office files while he was president. These files contain correspondence, reports, newspaper clippings, transcripts and press releases. There is correspondence between Rusk and then Secretary of State John Foster Dulles, former President Harry Truman, Henry Kissinger, Rockefeller Foundation Director of Special Studies, and Rockefeller family members Nelson, Laurance, David and John D. Most of the files deal with the foundation's work in the area of foreign relations, as well as Rusk's confirmation hearings when he became Secretary of State.
