Günter Wirths

Günter Wirths (1 June 1911 – 26 January 2005) was a German nuclear chemist in the former Soviet program of nuclear weapons and an authority on the uranium metal production, especially on the reactor-grade.

Until the fall of Berlin in 1945, Wirths was employed with the ''Auergesellschaft AG'' in the production of uranium for the ''Heereswaffenamt'' as part of their ''Uranverein'' club.

After taken into the Soviet custody, he became one of many German nuclear physicists who were involved in the former Soviet program of nuclear weapons in Russia and returned to Germany in 1955 where he later worked at the Degussa AG chemical company. Provided by Wikipedia
