Racist author and Nordic supremacist Hans F. K. Günther, who influenced Nazi ideology, wrote in his "Race Lore of German People" ("Rassenkunde des deutschen Volkes") about the danger of "Slavic blood of Eastern race" mixing with the German and combined virulent nationalism with anti-semitism. Günther became an epitome of corrupt and politicized pseudo-science in post-war Germany. Among the topics of his research were attempts to prove that Jewish people had an unpleasant "hereditary smell". While one of the most prominent Nazi writers, Günther still was not considered the most "cutting edge" by Nazis.
