This collection of declassified documents pertaining to the creation of the first atomic bombs contains selected correspondence of Major General Leslie Groves, commander of the Manhattan Engineering District from 1942 to 1946. The documents were chosen because of their particular connection to General Groves or because of their originally high security classification. They consist of letters, reports, and memoranda on five rolls of microfilm, with some dated as late as 1950. The subject matter includes the technical, scientific, and fiscal issues related to producing the atomic bombs, relations with allied governments concerning nuclear affairs, preparations for and results of the atomic bombing of Hiroshima and Nagasaki, the Alsos missions to Italy and Germany, relations with Congress and private industry involved in the Manhattan Project, the status of foreign scientists involved in the project, and legislation for postwar development and control of nuclear power. The collection is an important source of primary documents, and would be most useful to persons researching the history of the Manhattan Project.
