I think that this statement should have been more clearly written. While German universities may have helped spread the ideals of Nazism, it is wrong to say that it was the "originator" of Nazism. Hitler, in response to the Versailles Treaty, was the originator of Nazism. I don't recall ever hearing about Hitler studying at a university and then deciding to form the Nazi party. I don't recall ever even hearing about Hitler even attending a school of higher learning. He was refused by an art school though.
I don't mean to nit pick, but I disagree with this premise. The Nazi movement began, and grew powerful, thanks to uneducated street thugs and disaffected military veterans.
Geographer Hans Haushofer and his theories of "living space" were widely debated even before Hitler came to power. In fact Hitler was influenced by Haushofer, and not vice versa. The German interest in "geopolitics" was so pervasive that following WWII the term was practically erased from the geographic lexcon and from an academic's vocabulary.
