If you want to go a university in Germany or Austria and get rich afterwards, the website Wealth-X has a ranking for you. It counts the number of UHNW (ultra high net worth) alumni, those with US$ 30 million or above.
Here are the top five with the number of UHNW individuals in brackets.
1. University of Cologne (18)
2. University of Munich (14)
3. University of Hamburg (13)
4. University of Freiburg (11)
5. University of Bonn (11)
There may well be protests about who should be first. In tenth place is "Ludwig Maximilians University Munich (LMU Munich)", which I assume is another name for the University of Munich, with six UHNW alumni .
