Hi,  
I am convinced rgar I have read somewhere that Bismarck and Mangoldt had some  
contacts in 1868. The story told was that a foreseen meeting was cancelled    
or postponed because of Bismark was sick and eventually never took    
place because of Mangoldt's death. Unfortunately I cannot find my    
source again and wonder if I dreamt it.
