Aage Bohr

Aage Bohr, the twenty-one-year-old son of Niels Bohr, was a promising physicist who accompanied his father into the British-American atomic-bomb project’s orbit. His wartime journey took him from London to the United States and then Los Alamos, where he was present as his father raised questions about the German program and the future consequences of the bomb.

Identity and Arrival

A week after Niels Bohr reached London in 1943, Aage joined him there. The book identifies him as a promising young physicist who would later earn a Nobel Prize in his own right. His presence made the journey to the bomb project a father-and-son undertaking, though the account does not assign him a separate scientific intervention at this stage.

Briefing and Journey to America

Over the following seven weeks, Aage and his father were thoroughly briefed about Tube Alloys, the British code name for the bomb project. Niels Bohr agreed to serve as a British consultant, and the British then arranged for the pair to travel to America. They sailed for New York in early December. General Groves was reluctant to allow Niels Bohr to visit the secret laboratory in New Mexico, but ultimately granted permission for the visit, in view of the physicist’s standing among scientists.

Los Alamos and the German Program

Aage arrived with his father at Los Alamos late on December 30, 1943, and attended a meeting convened the next day. Niels Bohr described his 1941 meeting in Copenhagen with Werner Heisenberg, who was leading Germany’s nuclear-bomb effort. The meeting brought the Bohrs together with leading Los Alamos scientists to consider what Heisenberg had said about uranium and the technical feasibility of a weapon. Aage’s documented role is that of a young physicist present at this consequential exchange: the narrative places him beside his father as the German project’s uncertain prospects became a matter of direct concern at Los Alamos.
