Q:

What did Julius Lippert lecture on after WWII?

Julius Lippert was a Nazi top functionary (mayor of Berlin till he was demoted and fell out of grace) and a convicted war criminal. However, wiki tells us:

He lectured at universities until his death on 30 June 1956, in Bad
  Schwalbach.

What did he lecture about? Where? 

A:

I found this:

Bis zu seinem Tode hat Julius Lippert in Bad Schwalbach Vorträge über Kunstgeschichte gehalten.

Translation mine:

Until his death, Julius Lippert held lectures on art history in Bad Schwalbach.

The location seems inconsistent ("at universities" -- "in Bad Schwalbach", perhaps they confused location of death with the location of his lectures), but at least the subject seems clear - art history.
