You underestimate academia. Any academic that reads these two sentences only focuses on the first one: He has a named chair at Courant. In Germany, being a a Prof is added to your ID card/passport and becomes part of your official name, like knighthood in other countries.

No true regarding the IDs, only PhD titles can be added. Not job descriptions. Source: academia person in Germany.

It seems Germans add their PhD titles even to their nicknames. :)
