What was the specific contribution of the scientists at the KWI at Heidelberg with regards to the effect of the nerve gases? At the KWI Kuhn and his collaborator Konrad Henkel invented the nerve gas Soman in 1944. Much stronger than all other nerve gases known by then, Soman was treated as a so-called new "Wunderwaffe" (wonder-weapon) of the Nazi-leadership.
