Neumann's factory in Berlin was damaged by Allied firebombing in November 1943. Georg Neumann relocated his company to the much smaller town of Gefell in Thuringia and resumed production at the beginning of the following year. At the close of the war, Thuringia fell under Soviet control and the company eventually became an East German "Publicly Owned Operation" (i.e. a state-run enterprise). After the reunification of Germany, the company in Gefell, which had continued to use the Neumann name, became known as Microtech Gefell.
