Felix Krueger (or Krüger) (10 August 1874 in Posen; - 25 February 1948 in Basel) was a German psychologist and professor at the University of Leipzig.
In 1929 he belonged to the founding members of Alfred Rosenberg's Militant League for German Culture.
When the Nazis seized power in 1933 Krueger wrote: “This is not only about the future of Germany.
Ethics and thus the life of the white race are at stake.”The Nazi authorities eventually later found out that his grandfather was a "full-blooded Jew."
