Henry D. Smyth was a professor of physics and chairman of the physics department of Princeton University from 1935 to 1949. [1] During World War II, he was involved in the Manhattan Project from early 1941, initially as a member of the National Defense Research Committee's Committee on Uranium, and later as an associate director of the Metallurgical Laboratory in Chicago.
More than 50 of the initial signatories worked in the Chicago branch of the Manhattan Project. After much disagreement among the other scientists in Chicago, lab director Farrington Daniels took a survey of 150 scientists as to what they believed the best course of action would be, regarding the bomb.
The Los Alamos Primer is a printed version of the first five lectures on the principles of nuclear weapons given to new arrivals at the top-secret Los Alamos laboratory during the Manhattan Project. The five lectures were given by physicist Robert Serber in April 1943. The notes from the lectures which became the Primer were written by Edward ...
As government documents have been declassified and historians have examined archives and collected oral histories, the work of people like physical chemist William Jacob Knox Jr., chemist Lloyd Quarterman, physicist Carolyn Parker, physicist and mass spectrometrist Robert Johnson Omohundro, and physicist and mathematician Jesse Ernest Wilkins ...
After the selective transcriptions had been made, the discs and recordings were destroyed. The transcripts were sent as reports to London and the American consulate, and were then forwarded to General Leslie Groves of the Manhattan Project [3] in 24 reports, over 250 pages. In February 1992 the transcripts were declassified and published.
The Franck Report of June 1945 was a document signed by several prominent nuclear physicists recommending that the United States not use the atomic bomb as a weapon to prompt the surrender of Japan in World War II. The report was named for James Franck, the head of the committee that produced it.
This information allowed the Soviet scientists a first-hand look at the setup of a successful atomic weapon built by the Manhattan Project. The most influential of the atomic spies was Klaus Fuchs. Fuchs, a German-born British physicist, went to the United States to work on the atomic project and became one of its lead scientists.
