[2] After his release from the Soviet custody, he returned to Germany after accepting the teaching position as professor of mechanical engineering at the University of Magdeburg.

[3][circular reference] His father, a banker, supported his studies when he went to attend the Dresden University of Technology and graduated with engineering degree in 1937.

The group included the physicists Walther Bothe, Robert Döpel, Hans Geiger, Wolfgang Gentner, Wilhelm Hanle, Gerhard Hoffmann, and Joos.

The second Uranverein began after the Heereswaffenamt (HWA, Army Ordnance Office) squeezed out the Reichsforschungsrat (RFR, Reich Research Council) of the REM and started the formal German nuclear energy project.

When it was apparent that the nuclear energy project would not make a decisive contribution to ending the war effort in the near term, control of the KWIP was returned to its umbrella organization, the Kaiser-Wilhelm Gesellschaft (KWG, after World War II renamed the Max-Planck Gesellschaft) in January 1942 and control of the project was relinquished to the RFR that year.

)[12][13] On 5 March 1946, in order to staff his laboratory, Pose and NKVD General Kravchenko, along with two other officers, went to Germany for six months to hire scientists.

Additionally, Pose procured equipment from the companies AEG, Carl Zeiss AG, Schott Jena, and Mansfeld, which were in the Russian occupation zone.

Three heads of laboratories, Czulius, Herrmann, and Rexer, were Pose's colleagues who worked with him at the German Army's testing station in Gottow, under the Uranverein project.

Eight laboratories in the institute were:[12] When his time with the Soviet Nuclear Program was done, Herrmann returned to the DDR to focus on restoring the country's energy supply.

As recognition for his service, and skill at restoring energy in the DDR Herrmann was sent to Hungary to manage the commissioning, designing, and construction of power plants.
