Leo Szilard invented the atomic fission bomb in 1933 while in London, and patented it in 1934. However no material that fissioned was known at the time, so the bomb was not possible to build at that time.
Otto Frisch discovered fission of Uranium-235 in 1938 while in Berlin, making the atomic fission bomb possible. However Uranium-235 is only 0.72% of natural Uranium and purifying it is difficult and expensive, so an atomic fission bomb could not be built immediately.
The US Manhattan Project built the expensive industrial infrastructure it purify Uranium-235 and manufacture Plutonium-239 between 1942 and 1945. Resulting in a usable atomic fission bomb by 1945.
