I basically mean the Director of the University where Hitler did not get into in his youth. What happened to him in the 1930-1940s. If he was still alive at that point did Hitler had some sort of revenge on the university that lead to Hitler as we know him?
The name you are looking for is Alfred Roller and apparently Hitler did not hold a grudge since he supported him (appointing him to a position at the prestigious Wagner festival in Bayreuth) until his death in 1935.
Hitler was known to be a big fan.
