The Manhattan Project

The following documents demonstrate the tremendous concern of the Association of Manhattan Project Scientists toward nuclear power in peacetime. On the right is one of many drafts that shaped a collective statement from the scientists released just after the war. These drafts were edited by Dr. Francis Bonner and Dr. Irving Kaplan, lead scientists who worked intimately with Nobel Prize chemist Dr. Harold Urey in the development of the atom bomb.
This letter, written by Dr. Francis Bonner in 1945, outlines the activity of the Manhattan Project Scientists in New York and Washington. It notes the proposed May-Johnson Bill, which was being submitted to the House of Representatives. If passed, this bill would have turned over the bulk of nuclear research to the military. The scientists opposed the bill because they believed atomic energy research was a global concern.
Dr. J. R. Dunning circulated this internal "restricted" letter just months prior to the bombing of Hiroshima. It was distributed to an engineering department (called S.A.M. Laboratories and located at Columbia University) that was working on the Manhattan Project. The letter thanks members for their outstanding work and dedication to the project. This copy belonged to Mildred Goldberg, a secretary, who unknowingly typed out scientific formulas for this top secret wartime operation and later collected the documents contained in this exhibition.

Shown here are memoirs of Mildred Goldberg, recalling the friendly and inspirational work environment that she experienced while serving as secretary for the Manhattan Project scientists. These recollections provide direct insight into the inner workings of a historic scientific community.
