This series reflects primarily the activities of John D. Rockefeller, Jr., but significant documentation on the political and civic concerns of each of his sons is also present. In addition to extensive files on family support of the Republican Party on the national, state, and local level, separate folders exist on specific candidates, such as President Dwight D. Eisenhower, New York City Mayor Fiorello La Guardia, and New York Governor Thomas Dewey. There are substantial files on family support for Nelson Rockefeller during his first gubernatorial campaign and immediately afterward. However, very little material exists in this series on his presidential effort in 1960.

The Office of the Messrs. Rockefeller (OMR) materials document the increasing role assumed by John D. Rockefeller, Jr. in the management of Rockefeller affairs and amply document his business and philanthropic affairs. They also chronicle the entrance of JDR Jr.'s sons, John D. 3rd, Nelson A., Laurance S., Winthrop, and David, into the world of business, philanthropy, civic leadership, and politics as they joined the office.

The files found in this series include correspondence by members of the Rockefeller family and their representatives and the officials of various institutions. Most of the material is unsolicited requests for aid. The material on institutions in which the family took an active interest, such as the International Houses, includes analysis, reports, general correspondence, contributions, and administration.
