Los Alamos, where Niels Bohr visited the Manhattan Project, was in New Mexico.
During the Second World War, Los Alamos served as the secret laboratory where scientists coordinated the design of the first atomic bombs. Bohr reached the United States after fleeing German-occupied Denmark through Sweden and Britain. He visited Los Alamos as a British consultant and adviser, bringing expertise in nuclear physics and information about developments in Europe.
For security reasons, Bohr used the pseudonym “Nicholas Baker” in the United States. His son Aage accompanied him and used the name “James Baker.” The site’s remote location in northern New Mexico helped protect the enormous wartime research effort from public attention.
Los Alamos is often confused with Oak Ridge, Tennessee, another major Manhattan Project location. Oak Ridge focused heavily on uranium enrichment, while Los Alamos concentrated on weapon design. The first nuclear test, Trinity, took place elsewhere in New Mexico, near Alamogordo, on 16 July 1945.
