George L. Harrison and Harvey H. Bundy were two special assistants to Secretary of War Henry L. Stimson. The Harrison-Bundy Files, also known as the Arneson Files, document the Army's role in the development and production of nuclear weapons. The files date from 1940 to 1950, with most documents dating from 1942 to 1946.
Harrison and Bundy served as liaisons between Stimson, Brig. Gen. Leslie R. Groves of the Army Corps of Engineers, and other officials participating in the Manhattan Engineer District Project. Harrison was a special consultant to the Secretary of War from 1943 to 1947 and served as an alternate chairman of the Secretary's Interim Policy Committee on Atomic Energy. Bundy was a special assistant to the Secretary of War from April 1941 to September 1945. Capt. R. Gordon Arneson served as administrative secretary to the special assistants and maintained these files.
Most of the documents in the Harrison-Bundy Files consist of letters, reports, and memorandums. Other types of records include: messages; telegrams; directives; notes; minutes and agenda of meetings; histories; draft and published copies of speeches, press releases, legislation, and international agreements; petitions; maps and charts; receipts for documents; and miscellaneous printed material.

The History of Atomic Bomb
Although created and maintained in the Office of the Secretary of War, these records are now stored in the National Archives among those of the Manhattan Engineer District, which are part of the collection Records of the Office of the Chief of Engineers, Record Group (RG) 77.
Secretary of War Stimson maintained custody of the Harrison-Bundy Files until his retirement in September 1945, at which time he transferred them to Groves. Groves subsequently incorporated the files with those records of the Manhattan Engineer District of which he retained custody. When Groves became Chief, Armed Forces Special Weapons Project, he maintained the files in the custody of the Project. This practice was continued during the tenures of his successors, Gen. Kenneth D. Nichols and Gen. Herbert B. Loper.
Upon General Loper's retirement, the records were removed to the custody of General Nichols, then Chief, Research and Development, Office of the Army Chief of Staff. When Nichols retired in 1953, the files were transferred to the physical custody of the Adjutant General of the Army, under arrangements made by Groves with the Office of the Army Chief of Staff. In 1958, they were transferred, along with many other Army records, to the custody of the National Archives and Records Service (NARS) in Alexandria, Va. Physical transfer to the National Archives Building, Washington, D.C., was made in 1968.
The files in this set are reproduced in the order they are kept at the National Archives. The Harrison-Bundy Files are arranged in 113 folders according to a subject-numeric scheme. The disc contains numerical and alphabetical lists of folder headings. A number of duplicate documents were retained in the files, as noted in the accompanying Armed Forces Special Weapons Project (AFSWP) created lists for the folders. An effort was made to not reproduce in this collection the duplicate copies.
Within individual files, documents are arranged in accordance with accompanying descriptive lists prepared by the Armed Forces Special Weapons Project (AFSWP). The lists for each folder are placed at the being of the documents in each folder for use as a finding aid for the documents, which follow.
