Nazi propaganda was produced to manipulate the public, most notably based on writings from people such as Eugen Fischer, Fritz Lenz and Erwin Baur in Foundations of Human Heredity Teaching and Racial Hygiene. The work Die Freigabe der Vernichtung lebensunwerten Lebens (Allowing the Destruction of Life Unworthy of Living) by Karl Binding and Alfred Hoche and the pseudo-scholarship created by Gerhard Kittel also played a role. In occupied France, the collaborationist regime established its own Institute for studying the Jewish Questions.
