#Wikipedia - Professor Hermann Buhl "Leichtathlet"

Mr Buhl died in Tirol wandering through the Alps.  He used to be an athlete of repute and became a professor at the Julius Maximilians-Universiteit.

It is obvious that Mr Buhl was a professor because of his presence in a category. It is not obvious in the same way where he studied and what he taught. When you read the text, it expects a lot of knowledge about the DDR for the text to make such things obvious.

Every Wikipedia has its notability criteria and, the German Wikipedia is not different. Mr Buhl is certainly notable as an athlete but his career did not end. He is probable notable as well for the "latter" part of his career. Some would argue that he started to contribute in a meaningful way when he taught in university.
