I want to know the answer to the following question:
Which Prussian linguist called for an anthropology?
All the background I'm provided with is that "During the Romantic era, scholars in Germany, especially those concerned with nationalist movements—such as the nationalist struggle to create a "Germany" out of diverse principalities, and the nationalist struggles by ethnic minorities against the Austro-Hungarian Empire—developed a more inclusive notion of culture as "worldview" (Weltanschauung).". Is that enough to answer the question?
Answer: no
