Nobody. If you are thinking of Einstein's work on relativity, all it said was that lots of energy was inside matter but no suggestion was made as to how to get it out or even if it was possible to get it out. Also Einstein did not work on the project as he was both a pacifist and would not work on any war related projects and was considered an enemy alien by the Army's people responsible for granting security clearances. The first appearance of atomic bombs in literature was in 1914 in H. G. Wells Science Fiction novel The World Set Free.
Leo Szilard invented the way to get it out (neutron chain reaction) in 1933 and was granted a patent for it in 1936, but no material was known then that would support this process. A team working in Germany and Sweden discovered in 1939 that the isotope uranium-235 fissioned when struck by neutrons and also released an excess of neutrons, making it suitable to support a neutron chain reaction.
The atomic bomb was not developed in 1939. The Manhattan Project operated from 1942 to 1947 and did not build any until the summer of 1945.
Albert Einstein developed a Theory of Relativity which helped lead to the development of atomic energy. He also worked on the Manhattan Project to help create the world's first nuclear bomb.

Relativity was 1905, various "atomic" theories go back 2500 years to the Greeks.

John Dalton first pursued research into atomic theory. He was the first person to propose the existence of the atomic structure.

Neil bohr has done research in quantum mechanics.

His theory about atomic fusion helped in the development of the bomb. He also convinced the president to develop the research in it. In the last 25 years of his life he questioned himself concerning the use and development of the bomb and was unhappy that he had helped build the theory and foundation of atomic theory.
