Named in memory of an anti-Nazi resistance group formed in 1942 in Silesia at the Kreisau farm, the family estate of H. J. Graf von Moltke. The members of the group, called Kreisauer Kreis, were mainly conservative people from a variety of social backgrounds and political attitudes. They considered the possibility of eliminating the fascist regime and revising Germany's ethical and political character. Most of the members were executed following the assassination attempt on the fascist leader in July 1944. Name proposed by the first discoverer.
