ABSTRACT

This chapter discusses “Copenhagen” by first examining the postwar construction of the visit by various actors for various reasons, and then scrutinizing the actual history in context. In March of 1941, Ernst von Weizsacker travelled to occupied Copenhagen. In September of 1941, the German physicist Werner Heisenberg visited his Danish mentor Niels Bohr in occupied Denmark. The technical production of energy from uranium fission is not being worked on in Copenhagen. After the war, Heisenberg claimed that he had travelled to Copenhagen in order to forestall all nuclear weapons. In contrast, after the war, Bohr claimed that Heisenberg had told him that Germany was going to win the war, if necessary with nuclear weapons. Werner Heisenberg went, not only to the Copenhagen astrophysics workshop, rather also to many other places, gave similar talks, and behaved in a similar fashion.
