In Los Alamos, New Mexico, Manhattan Project administrators found an ideal location for the secret laboratory where they designed and built the world’s first atomic weapons. During the Manhattan Project, Los Alamos became the home to many of the top scientific minds of the day: J. Robert Oppenheimer, Norris Bradbury, Richard Feynman, Hans Bethe, and many more luminaries. These scientists worked together to develop the theoretical and experimental tests that created the first atomic weapons, using enriched uranium from Oak Ridge and plutonium from Hanford. Today, the nucleus of this once-secret city is still Los Alamos National Laboratory. Explore the people, places, and stories of Los Alamos to learn more about this once secret community.
