Leo Szilard, a Hungarian Jew living in London at the time, in 1933. He patented it in 1934, the patent GB630726 was granted in 1936 and immediately classified to prevent Nazi Germany from using it. It took 12 more years before the US was able to build the first ones, after an enormous investment in industrial infrastructure. Szilard's patent was not made public until 1949. During WW2 this was done under the Manhattan Project. There was a large team of scientists, the chief one was Dr Robert Oppenheimer.
Professor Rudolph Peierls and Otto Frisch were also involved.
The atomic bomb was originally invented in 1940 by German scientists, Professor Rudolph Peierls and Otto Frisch who were both working for Britain at the time.
During World War II, the United States, with the assistance (collaboration) of physicists, mathematicians, and engineers from the U.S., Britain, Canada and Europe, completed the Manhattan Project to produce the first atomic bomb.
(The project started as the "Manhattan District Engineers" and only became "The Manhattan Project" some time later).
There was some early speculation about the possibility of what could be done if a nuclear chain reaction was unleashed in a way that would allow it to build without control. For a roll call, consider that Robert Oppenheimer was the head of "science" for the Manhattan Project, and (in alphabetical order) Felix Block, David Bohm, Niels Bohr, Enrico Fermi, James Franck, Otto Frisch, Klaus Fuchs, Rudolf Peierls, Emilio Segre, Leo Szilard, Edward Teller and Eugene Wigner all played crucial roles in getting the weapon designed and built.
The physicist Albert Einstein did not participate directly in the invention of the atomic bomb-but was instrumental in facilitating its development. His Special Theory of Relativity emphasized that a large amount of energy could be released from a small amount of matter. This was expressed by the equation E=mc2 (energy = mass times the speed of light squared). The atomic bomb would clearly illustrate this principle.
The first demonstration of "the gadget" (the code name for the first atomic bomb) was at Trinity site in Alamogordo, New Mexico, and it proved that the weapon would detonate and that the chain would build as predicted. The second and third demonstrations were conducted in Japan, which brought a quick end to the Second World War. Just up to and during World War 2, Germany was also working to develop atomic weapons, but was hampered by many technical and political problems (including sabotage and Allied bombings) which prevented their successfully completing their work. This left the U.S. as the only nation to ever unleash nuclear weapons in an attack.
The first fission weapons, also known as "atomic bombs," were developed jointly by the United States, Britain and Canada during World War II in what was called the Manhattan Project. (Wikipedia)
Leo Szilard invented the atomic bomb in 1933 while crossing a London street. He patented it in 1934. (British patent 630,726)
The Manhattan Project built the first one in 1945.
