Robert Oppenheimer is often considered the "father of the atomic bomb" for his role as the scientific director of the Manhattan Project, which resulted in the development of the first nuclear weapons used in World War II: the atomic bombs dropped on Hiroshima and Nagasaki in 1945. Oppenheimer did not personally make the nuclear weapons but played a critical role in their development.
The bomb was not made in 1939. It was made in 1945 at the end of WW2. Oppenheimer did not make the bomb, a very large group of scientists and technicians made the bomb. Oppenheimer was the civilian head of the group. That is analogous to saying that a single person invented the rocket that took men to the moon.
He was attempting to do just that- make an atomic bomb.
The atomic bomb was created by a team of scientists led by J. Robert Oppenheimer at the Manhattan Project during World War II. Oppenheimer is often credited as the "father of the atomic bomb" for his leadership in the project.
Albert Einstein did not make the nuclear bomb. Oppenheimer did.
The atom bomb research and development were conducted under the Manhattan project.
to make the atom bomb seem less threatning.
