Leo Szilard in 1933 in London. He could not build it at the time for many reasons, but he invented it. It took another 12 years and an investment of $2,000,000,000 before the first ones could be built.

No, he was a pacifist and worked on no war projects. His only involvement with the atomic bomb was to sign a letter to FDR that Leo Szilard had written, warning that the Nazis might make one first.The atomic bomb was not invented in the US, it was invented in London, England in 1933 by Leo Szilard while crossing a street and patented by him in 1934.
