Concept note-1: -Manhattan Project, U.S. government research project (1942–45) that produced the first atomic bombs. American scientists, many of them refugees from fascist regimes in Europe, took steps in 1939 to organize a project to exploit the newly recognized fission process for military purposes.
Concept note-2: -Eight months after the United States entered World War II, the federal government launched the Manhattan Project, an all-out, but highly secret, effort to build an atomic bomb – and to build one before the Germans did.
Concept note-3: -President Truman authorized the use of the atom bombs in an effort to bring about Japan’s surrender in the Second World War. In the days following the bombings Japan surrendered. The Manhattan Project was the US government program during World War II that developed and built these first atomic bombs.
Concept note-4: -Project Y was the designation for the top-secret design and production of the atomic bombs for the Manhattan Project. General Leslie Groves, director of the Manhattan Project chose Robert Oppenheimer, a theoretical physicist, to lead Project Y, which is today better known as Los Alamos.
