On 10 December 1946, the anniversary of the death of Alfred Nobel, King Gustav V of Sweden presented him with his Nobel Prize medal and diploma. Hahn gave 10,000 krona of his prize to Strassmann, who refused to use it.

After his return to Germany, he assumed the office on 1 April 1946. Allied Control Council Law No. 25 on the control of scientific research dated 29 April 1946 restricted German scientists to conducting basic research only, and on 11 July the Allied Control Council dissolved the KWS on the insistence of the Americans, who considered that it had been too close to the national socialist regime, and was a threat to world peace. However, the British, who had voted against the dissolution, were more sympathetic, and offered to let the Kaiser Wilhelm Society continue in the British Zone, on one condition: that the name be changed. Hahn and Heisenberg were distraught at this prospect. To them it was an international brand that represented political independence and scientific research of the highest order. Hahn noted that it had been suggested that the name be changed during the Weimar Republic, but the Social Democratic Party of Germany had been persuaded not to. To Hahn, the name represented the good old days of
