Claim: Günter Wirths, along with eleven other German scientists including German-Russian medical doctor H. J. Born, were sent by the Soviets at the close of World War I to work in the Riehl group at Plant No.
Evidence: Near the close of World War II, as American, British, and Russian military forces were closing in on Berlin, Riehl and some of his staff moved to a village west of Berlin, to try to ensure occupation by British or American forces. From 1945 to 1950, Riehl was in charge of uranium production at Plant No.
