Manhattan District History: Book I - General; Volume I - General, Hardcover

The original contemporaneous history of the Manhattan project written by the Manhattan District team. An essential reference for anyone interested in one of the most important events of the 20th Century and indeed in human history. There is no better way to understand the past than to read the actual words of those who lived it.

General Leslie Groves, head of the Manhattan Engineer District, in late 1944 commissioned a multi-volume history of the Manhattan Project called the Manhattan District History. Prepared by multiple authors under the general editorship of Gavin Hadden, a longtime civil employee of the Army Corps of Engineers, the classified history was "intended to describe, in simple terms, easily understood by the average reader, just what the Manhattan District did, and how, when, and where." The volumes record the Manhattan Project's activities and achievements in research, design, construction, operation, and administration, assembling a vast amount of information in a systematic, readily available form. The Manhattan District History contains extensive annotations, statistical tables, charts, engineering drawings, maps, photographs, and detailed indices. Only a handful of copies of the history were prepared. The Department of Energy's Office of History and Heritage Resources is custodian of one of these copies.

The history is arranged in thirty-six volumes grouped in eight books. Some of the volumes were further divided into stand-alone chapters. Several of the volumes and stand-alone chapters were never security classified. Many of the volumes and chapters were declassified at various times and were available to the public on microfilm. Parts of approximately a third of the volumes remain classified.

The Office of Classification and the Office of History and Heritage Resources, in collaboration with the Department's Office of Scientific and Technical Information, have made the full-text of the entire thirty-six volume Manhattan District History available on this OpenNet website. Unclassified and declassified volumes have been scanned and posted. Classified volumes were declassified in full or with redactions, i.e., still classified terms, phrases, sentences, and paragraphs were removed and the remaining unclassified parts made available to the public.
