The Manhattan Project would ultimately yield the “Little Boy” and “Fat Man” bombs that released more than 100 Terajoules of energy at Hiroshima and Nagasaki, but as it turned out, the Axis were not far behind with their own nuclear weapons program. When the Nazis’ quest for a nuclear weapon began in earnest in 1939, no one really had a handle on how important nuclear weapons would prove to war and geopolitics. The pursuit of nuclear weapons moved the scientist nearer to the role of combatant, placing special responsibilities on the scientific community to make critical moral decisions. However, as they developed atomic weapons, they could at the same time only warn military powers of their use. Advocates for nuclear power as a civilian energy resource but expressing misgivings about nuclear war put them at odds with uninformed branches of the military. 

Niels Bohr was a world-famous physicist and one of the patriarchs of quantum theory. Given the vibrant, peaceful haven that is Denmark today, it’s somewhat ironic that Bohr played an instrumental role in the development of the atomic bomb. Even so, the truth and depth of the matter, much like the self-professed pacifist himself, is far more complex.

The American war effort against the Japanese and Germans also included denying either one the use of a practical nuclear weapon. Physics was in its highest stage of advancement in Europe during this time, while J. Robert Oppenheimer emerged as an extraordinary scientific mind in the United States. Despite requiring the work of thousands of scientists and assistants in fashioning the weapon that eventually came to pass, Oppenheimer alone has been become renowned as the “father of the atomic bomb” due to his leadership of the Manhattan Project.
