John J. McCloy (AC 1916) Papers

Identifier: MA.00035

Scope and Contents

The John J. McCloy Papers span the years 1897-1989, with the bulk of the material falling into the period 1940-1979. The roughly 74 linear feet of material cover the breadth of McCloy's activities, from lawyer to banker to government official to negotiator to behind-the-scenes adviser. The papers include working papers, correspondence and memoranda, speeches, scrapbooks, photographs, legal documents, printed material, and memorabilia. The collection includes very little personal or family-related material.

The first six series consist of materials, grouped by topic or type, that span much or all of McCloy's public career: Personal Affairs, Diaries, Scrapbooks, Speeches, Awards, and Photographs. The next 25 series consist of "working papers," divided according to McCloy's various positions, roles, and areas of influence. Series 32 consists of printed material of a general nature. (Printed material related to a given position is included in the relevant series.) Series 33: Correspondence and Series 34: Retrospectives contain unofficial correspondence and biographical material, which arrived as part of the second installment to the Papers.

More detailed description can be found at the series level. Series-level scope and content notes include: historical and biographical information; series and sub-series arrangement; subject matters and formats, and a box/folder listing.

Immediate Source of Acquisition

The John J. McCloy Papers were given to Amherst College by McCloy through a deed of gift executed in July of 1985. Prior to their physical transfer to the Amherst College Archives, roughly half of the papers underwent a national security review by the Department of State. The bulk of these arrived at the College in May of 1986, with several batches sent later following clearance by the relevant government agency.

Related Materials

Because of John McCloy's longtime connections with the college, the Amherst College Archives has information about him beyond that found in his own papers. Sources include the Biographical Files (Class of 1916), the Photographic Images Collection, the Buildings and Grounds Collection (especially the files on the War Memorial and the Frost Library), and publications such as the Olio (the yearbook), the Amherst Student (the student newspaper), and the alumni magazine. Contact the Amherst College Archives for further information.

Other institutions holding primary source material include: the National Archives, the Presidential libraries, the Ford Foundation, and repositories holding the papers of McCloy's associates.

Processing Information

Processing of this portion of the collection began in April 1986 and was completed in April 1990. In June 1990, after McCloy's death, the Archives received a second installment to the Papers. The processing of this addition required item-level attention, as the material had not been reviewed by the State Department. The Archives coordinated reviews by both the State Department and legal counsel. During this process detailed listings and cross-references were created to indicate the specific installment to which material belonged and to facilitate research use.

The papers were received in considerable disarray, with little evidence of their original order. Wherever possible, original groupings of items and folders were retained; however, the current organization of the papers was for the most part imposed during processing.

In 2017, the physical arrangement of the papers was revised. Folders were labelled contiguously and boxes were condensed in order to house the material safely and efficiently. The finding aid was revised to reflect new box and folder numbers and to clearly delineate physical and intellectual arrangement.
