This question already has an answer here:
I am surprised that some of the most historic universities in continental Europe are ranked above 100 on an average. I specifically have in mind University of Gottingen and University of Vienna. I am assuming that at the peak of their fame, they were rubbing shoulders with the best in the anglo-sphere. What caused the slide in reputation? I have heard that in Germany, Nazism caused the emigration of a lot of talented people. Or is it just that the ranking methodology is biased towards universities in the UK and the US? As someone interested in the history of scientists and scientific institutions, it seems somewhat odd.
