Ernest Rutherford, in 1919, was the first to split an atom, though it was nitrogen, and thus there was no power generation or explosion. In 1932 Sir John Cockcroft and Ernest Walton were the first to cause a nuclear reaction by the fission of an atom. Enrico Fermi, however was the first to fission uranium, in 1932, though at the time he did not fully appreciate the consequences of this discovery. Otto Robery Frisch and Lise Meitner were the first to realize the potential energy produced by the fission of uranium, however, and in a latter experiment, Frisch proved the theory.
The first person to ever realize its potential as a weapon, though, was the Hungarian physicist Leo Szilard, who realized, after experimentation, that the amount of neutrons released by the fission of uranium (two on average) could produce a nuclear chain reaction, which could lead to a massive explosion. Fearing the use of this reaction as a weapon by a facist government, however, Szilard kept his discovery secret, and convinced others to do the same, but the Joliot Curie group published the exact same results, coming to the same conlusion as Szilard.
However, the man who is generaly regarded as the "father of the A-bomb" is J. Robert Oppenheimer, who led the Manhattan Project in the United States, which produced the first ever nuclear weapon.
H.G. Wells was the first to envision a nuclear weapon driven by nuclear fission, when he wrote of "air dropped 'atomic bombs'" in his 1914 novel, The World Set Free. At the time, Wells did not know of the destructive power the such weapons would one day harness. Leo Szilard latter said that this novel had been the inspiration for his research on nuclear fission.And he has tested the bomb offensivly in japan
No one found it!
Leó Szilárd invented it in 1933 while living in London and patented it in 1934, his patent was granted in 1936 and the British Admiralty promptly bought the patent and classified it. However no fuel was known that could make the patent work to build an actual bomb.
In early 1939 a team of scientists working in Germany and Sweden discovered that one isotope of uranium (U-235) could fission when struck by a neutron and produce more neutrons that could cause more fissions. While these scientists did not know of Leó Szilárd's patent (as it was classified) they rapidly figured out everything Leó Szilárd had in 1933 now that they had a usable fuel.
In August 1939, prominent physicists Leó Szilárd and Eugene Wigner drafted the Einstein-Szilárd letter, which warned of the potential development of "extremely powerful bombs of a new type". It urged the United States to take steps to acquire stockpiles of uranium ore and accelerate the research of Enrico Fermi and others into nuclear chain reactions. They had it signed by Albert Einstein and delivered to President Franklin D. Roosevelt. Roosevelt soon authorized preliminary studies.
In 1942, with the United States now at war, Roosevelt decided to begin full scale development of these bombs and authorized the Manhattan Project.
In June 1944, the Manhattan Project employed some 129,000 workers but after construction was complete this declined to 100,000 workers.
The first bombs were ready in the summer of 1945.
Atomic Bomb
The city of Hiroshima was the place where the first atomic bomb was dropped.
august 6 1945 was the first and the second bomb was on august 9 1945.add. The first bomb exploded under the Manhattan Project was on July 16 1945, not long before the second and third bombs (above) were dropped in wartime.
I believe you are referring to Albert Einstein.
The location of the first atomic bomb which was dropped was on Hiroshima on August 6th 1945.
yes
yes we did
That there was a great danger if Germany did it first.
Pakistan is the first and still the only Muslim country to make atomic bombs.
No German scientist discovered the Atomic Bomb, so this question is meaningless. A Hungarian scientist, Leo Szilard, invented the Atomic Bomb in 1933 and he was already in London when he did it. It took 12 more years for the US to eventually make the first ones.
Leo Szilard.
Yes, both.
Atomic Bomb
Robert Oppenheimer.
They has fled the fascist government in Germany
The scientist given the most credit for the building of the atomic bomb is Robert Oppenheimer.
The atomic bomb is too expensive to develop for a city to have them. They are weapons held only by industrialized countries.
