Leo Szilard described the process of a nuclear chain reaction in 1933. Before then, the idea that elements could self-sustain a nuclear fission process after a single initial fission was unknown.
Szilard did experiments to verify this worked, and filed a patent for the description of a nuclear reactor in 1934. He immediately grasped the idea that a weapon could be built using the nuclear chain reaction principle.
In 1939, familiar with the German efforts to build a nuclear pile and possibly weaponize it afterwards, Szilard convinced Albert Einstein to send a warning letter to the US President, Franklin Roosevelt. This in turn resulted in the eventual creation of the Manhattan District project, and, in 1945, the production of the first functional atomic weapon.
