4 days ago · The first atomic bomb was detonated on July 16, 1945, in New Mexico as part of the U.S. government program called the Manhattan Project. The United States then used atomic bombs on Hiroshima and Nagasaki in Japan on August 6 and 9, respectively, killing about 210,000 people.
American physicist J. Robert Oppenheimer headed the Manhattan Project, with the goal of developing the atomic bomb, and Edward Teller was among the first recruited for the project. Leo Szilard and Enrico Fermi built the first nuclear reactor.
Nuclear physicist J. Robert Oppenheimer was the director of the Los Alamos Laboratory that designed the bombs. The Army program was designated the Manhattan District, as its first headquarters were in Manhattan; the name gradually superseded the official codename, Development of Substitute Materials, for the entire project.
Scientists played pivotal roles throughout the Manhattan Project. The Hungarian émigré theoretical physicists Leo Szilard and Edward Teller convinced Albert Einstein to write his letter to President Franklin Roosevelt in 1939 that initiated the government-supported research that would lead to the Manhattan Project.
