Willi Graf visits Karl Bisa
Before I left Bonn on Saturday morning, January 23, 1943, I was able to visit an old college friend named Karl Bisa, who resides with his mother at Luisen Str. 9. Bisa is also a member of the armed forces who has been furloughed to continue his studies. He is a member of the Student Company in Bonn.
