Medizin im Nationalsozialismus
Some of Lanz's proposals for racial purification anticipate the Nazis. The sterilisation of those deemed to be genetically "unfit" was in fact implemented under the Nazi eugenics policies, but its basis lay in the theories of scientific racial hygienists. The Nazi eugenics programme has no proven connection with Lanz's mystical rationale. Eugenic ideas were widespread in his lifetime, whereas he himself was banned from publishing in the Third Reich and his writings were suppressed.
