[edit] Education

Müller did graduate studies at the Friedrich-Wilhelms University (in 1949 renamed Humboldt University of Berlin). He received his doctorate at the Friedrich-Wilhelms University, under Carl Friedrich von Weizsäcker.^{[1] [2]}

[edit] Career

After 1939, Müller and Karl-Heinz Höcker collaborated with von Weizsäcker at the Kaiser-Wilhelm Institut für Physik (KWIP, after World War II reorganized and renamed the Max Planck Institute for Physics), in Berlin-Dahlem, on the theory behind the Uranmaschine (uranium machine, i.e., nuclear reactor).^[3]

Many at the KWIP and those working on the Uranmaschine had the classification of unabkömmlich (uk, indispensable) and were exempt from being drafted into armed service. Both Müller and his colleague Höcker had the classification uk, but their fates were quite different. As the war raged on, the demand for men to provide armed service resulted in Höcker and Müller being drafted in late 1940 or early 1941. Not even Kurt Diebner, managing director of the KWIP, could stop the call-up. Höcker was returned to the KWIP in 1942 due to poor health; Müller had died at the Russian front. It was not until 1944 that Werner Osenberg, head of the planning board at the Reichsforschungsrat (RFR, Reich Research Council), was able to initiate calling back 5000 engineers and scientists from the front to work on research categorized as kriegsentscheidend (decisive for the war effort). By the end of the war, the number recalled had reached 15,000. Many of the scientists called for military service were at institutes under the Kaiser-Wilhelm Gesellschaft (Kaiser Wilhelm Society).^{[4] [5] [6] [7]}

[edit] Internal Reports

The following reports were published in Kernphysikalische Forschungsberichte (Research Reports in Nuclear Physics), an internal publication of the German Uranverein. The reports were classified Top Secret, they had very limited distribution, and the authors were not allowed to keep copies. The reports were confiscated under the Allied Operation Alsos and sent to the United States Atomic Energy Commission for evaluation. In 1971, the reports were declassified and returned to Germany. The reports are available at the Karlsruhe Nuclear Research Center and the American Institute of Physics.^{[8] [9]}
