how the USA might have built the bomb. The Farm Hall transcripts reveal that Heisenberg, along with other physicists interned at Farm Hall including Otto Hahn and Carl Friedrich von Weizsäcker, were glad the Allies had won World War II. Heisenberg told other scientists that he had never contemplated a bomb, only an atomic pile to produce energy. The morality of creating a bomb for the Nazis was also discussed. Only a few of the scientists expressed genuine horror at the prospect of nuclear weapons, and Heisenberg himself was cautious in discussing the matter. On the failure of the German nuclear weapons program to build an atomic bomb, Heisenberg remarked, "We wouldn't have had the moral courage to recommend to the government in the spring of 1942 that they should employ 120,000 men just for building the thing up." Post-war research career Executive positions at German research institutions On 3 January 1946, the ten Operation Epsilon detainees were transported to Alswede in Germany. Heisenberg settled in Göttingen, which was in the British zone of Allied-occupied Germany. Heisenberg immediately began to promote scientific research in Germany. Following the Kaiser Wilhelm Society's obliteration by the Allied Control Council and the establishment of the Max Planck Society in the British zone, Heisenberg became the director of the Max Planck Institute for Physics. Max von Laue was appointed vice director, while Karl Wirtz, Carl Friedrich von Weizsäcker and Ludwig Biermann joined to help Heisenberg establish the institute. Heinz Billing joined in 1950 to promote the development of electronic computing. The core research focus of the institute was cosmic radiation. The institute held a colloquium every Saturday morning. Heisenberg together with was instrumental in the establishment of the Forschungsrat (research council). Heisenberg envisaged for this council to promote the dialogue between the newly founded Federal Republic of Germany and the scientific community based in Germany. Heisenberg was appointed president of the Forschungsrat. In 1951, the organization was fused with the Notgemeinschaft der Deutschen Wissenschaft (Emergency Association of German Science) and that same year renamed the Deutsche Forschungsgemeinschaft (German Research Foundation). Following the merger, Heisenberg was appointed to the presidium. In 1958, the Max-Planck-Institut für Physik was moved to Munich, expanded, and renamed Max-Planck-Institut für Physik und Astrophysik (MPIFA). In the interim, Heisenberg and the astrophysicist Ludwig Biermann were co-directors of MPIFA. Heisenberg also became an ordentlicher Professor (ordinarius professor) at the Ludwig-Maximilians-Universität München. Heisenberg was
