The Manhattan Project

The development of the atomic bomb was propelled by the urgency of World War II, particularly after the U.S. entered the conflict in December 1941. Key figures like Ernest proposed ambitious timelines for creating a nuclear chain reaction and bomb, while the project was officially named the Manhattan Project due to its initial offices in Manhattan. Major facilities were established in Oak Ridge, Hanford, and Los Alamos, setting the stage for groundbreaking advancements in nuclear technology.
