USA HISTORY

Detailed explanation-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.

Detailed explanation-2: -Early in 1939, the world’s scientific community discovered that German physicists had learned the secrets of splitting a uranium atom. Fears soon spread over the possibility of Nazi scientists utilizing that energy to produce a bomb capable of unspeakable destruction.

Detailed explanation-3: -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.

Detailed explanation-4: -Robert Oppenheimer (1904-1967) was an American theoretical physicist. During the Manhattan Project, Oppenheimer was director of the Los Alamos Laboratory and responsible for the research and design of an atomic bomb. He is often known as the “father of the atomic bomb.”
