Dean Professor or Dean and Professor

http://english.stackexchange.com/questions/180501/dean-professor-or-dean-and-professor?noredirect=1#comment374650_180501

If someone, called John, for example, has two titles that include Dean and Professor, which of the following expressions is better?

1. Dean Professor John visits Oxford University.
2. Dean and Professor John visits Oxford University.

best answer: 

Use one or the other. In English, we do not say "Herr Dekan Professor Doktor Johann", like they do in German. I would suggest using whichever capacity is related to his visit. –  Peter Shor 12 hours ago
