J. Robert Oppenheimer (born Julius Robert Oppenheimer; / ˈ ɒ p ən h aɪ m ər / OP-ən-hy-mər; April 22, 1904 – February 18, 1967) was an American theoretical physicist who served as the director of the Manhattan Project's Los Alamos Laboratory during World War II.
Soviet scientists such as Igor Kurchatov, L. D. Landau, and Kirill Sinelnikov helped establish the idea of, and prove the existence of, a splittable atom. Dwarfed by the Manhattan Project conducted by the US during the war, the significance of the Soviet contributions has been rarely understood or credited outside the field of physics ...
Sir Joseph Rotblat KCMG CBE FRS (4 November 1908 – 31 August 2005) was a Polish and British physicist. [2] During World War II he worked on Tube Alloys and the Manhattan Project, but left the Los Alamos Laboratory on grounds of conscience after it became clear to him in 1944 that Germany had ceased development of an atomic bomb.
He worked for the Manhattan Project's Metallurgical Laboratory at the University of Chicago on aspects of nuclear reactor design, where he was the chief physicist. He drafted the Szilard petition advocating a non-lethal demonstration of the atomic bomb, but the Interim Committee chose to use them in a military strike instead.
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 results were as follows:
