Willi Graf leaves class early
I had to leave the lecture about 10:50 am, because I had to be in the neurology clinic on Nussbaum Street by 11:15 am. I did not see the Scholl siblings when I left the university. If I had encountered them, it would not have escaped my notice, because it is not often that people enter the university carrying a suitcase.
