General Leslie R. Groves was in overall command of the project. Groves put J. Robert Oppenheimer in charge of the scientific work.

J. Robert Oppenheimer was the project lead scientist at Los Alamos, overseeing the design and construction of the first atom bombs in the early 1940s.
Edward Teller was in charge of making the first hydrogen bomb in the early 1950s and was involved with making the first atomic bomb, but it was Oppenheimer who was in charge, first.

Just before the First World War two German scientists, James Franck and Gustav Hertz carried out experiments where they bombarded mercury atoms with electrons and traced the energy changes that resulted from the collisions. Their experiments helped to substantiate they theory put forward by Nils Bohr that an atom can absorb internal energy only in precise and definite amounts.
In 1921 two Otto Hahn and Lise Meitner, discovered nuclear isomers. Over the next few years they devoted their time to researching the application of radioactive methods to chemical problems.
In the 1930s they became interested in the research being carried out by Enrico Fermi and Emilio Segre at the University of Rome. This included experiments where elements such as uranium were bombarded with neutrons. By 1935 the two men had discovered slow neutrons, which have properties important to the operation of nuclear reactors.
Otto Hahn and Lise Meitner were now joined by Fritz Strassmann and discovered that uranium nuclei split when bombarded with neutrons. In 1938 Meitner, like other Jews in Nazi Germany, was dismissed from her university post. She moved to Sweden and later that year she wrote a paper on nuclear fission with her nephew, Otto Frisch, where they argued that by splitting the atom it was possible to use a few pounds of uranium to create the explosive and destructive power of many thousands of pounds of dynamite.
In January, 1939 a Physics Conference took place in Washington in the United States. A great deal of discussion concerned the possibility of producing an atomic bomb. Some scientists argued that the technical problems involved in producing such a bomb were too difficult to overcome, but the one thing they were agreed upon was that if such a weapon was developed, it would give the country that possessed it the power to blackmail the rest of the world. Several scientists at the conference took the view that it was vitally important that all information on atomic power should be readily available to all nations to stop this happening.
On 2nd August, 1939, three Jewish scientists who had fled to the United States from Europe, Albert Einstein, Leo Szilard and Eugene Wigner, wrote a joint letter to President Franklin D. Roosevelt, about the developments that had been taking place in nuclear physics. They warned Roosevelt that scientists in Germany were working on the possibility of using uranium to produce nuclear weapons.

Who was I ? I was the person who suggested to a Committee to recognize Meitner in the early 1990s with her name on one element of the Periodic Table.
