who invented the first nuclear bomb
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.eo Szilard invented the nuclear reactor and nuclear bomb in London in 1933, shortly after the neutron was discovered as an improved source of neutrons for experiments. He was also very aware of their potential destructive effects. He was not able to build either at the time because of lack of a suitable material.
