Nobody, the basic invention of the neutron chain reactionwhich makes both atomic bombs and reactors possible was invented in 1933 by Leo Szilard while in London England. He applied for a patent on it in 1934, which was granted in 1936. However at that time no material was known that could support a neutron chain reaction.
A joint German/Swedish team discovered (without knowing of Leo Szilard's patent, which the British Navy had classified as soon as the patent was granted) that the element uranium-235 would undergo fission when struck by a neutron and also produce several neutrons. From this they independently invented the neutron chain reaction using uranium-235. At this point any physicist could see the basic principles for making atomic bombs.
However it still took many small inventions by many of the scientists and engineers working at Los Alamos to make practical and deliverable atomic bombs that could be used as weapons. As well as many more inventions needed to build and operate the uranium enrichment plants at Oak Ridge, TN and the plutonium production reactors and chemical purification plants at Hanford, WA.
Again, no single person at Los Alamos or anywhere else was responsible for inventing the atomic bombs designed and manufactured by the Manhattan Project. It was a task spread across the entire US, from coast to coast.

I believe it was Los Alamos Los Alamos was a town, it still is, no city developed the atomic bomb, it was a group of scientists that developed it.
Los Alamos was the name of a labroatory located in New Mexico which was used in the creation of the first Atomic bomb in WW2.
It is generally considered to be Los Alamos, New Mexico.

Los Alamos, it took dozens of workers.
