I'm guessing that Conan was referring to something from her book.CONAN: And indeed, this becomes important in Germany later, the battle between northern Germans, or the Prussians, if you will, who are from Weimar, and the soft, civilized, Romanized, if you will, Germans in Vienna.
Maybe he got the reference to Weimar backwards and was referring to the fourteen years of the Weimar era between WWI and the rise of Hitler in 1933. It was a brief comment and he may have fumbled it.
If I'm understanding correctly, there was a struggle between the softer Weimar culture (an intellectual explosion of creativity in science, technology, literature, philosophy and art) which stood in opposition to the harder Prussian militarism and authoritarianism. Some consider Vienna to have been part of this Weimar culture. Or Weimar might refer to the tradition of enlightenment liberalism in Germany with its origins in the 18th century city of Weimar, which were home to both Goethe and Schiller.
Or maybe not.
I did a search in the book on Amazon. She's talking writings by Christoph Meiners and J.F. Blumenbach from the late 18th century and early 19th, in which they develop a notions of race, part of which appears to deal with physical beauty, skull measurement, and skin color. It's important to note that she's critical of these writings. She also relates these ideas to the Holy Roman Empire and even Julius Caesar's understanding of the different Germanic tribes he was conquering.
She says that Meiners made a distinction between the northern Germans from Weimar, Dresden, Berlin, Hannover, and Göttingen (who were Protestant and who Meiners rated highly) and the southern Germans from Vienna (who were Catholic and Meiners did not rate well). She also relates Weimar to Goethe and Saxony, and describes three different of Saxony, including a mythical version that British and American "Anglo-Saxonists" flavored.
