Named for Johann Conrad Schlaun (1694–1773), baroque architect who worked mostly for the prince-bishop Klemens August of Köln. Schlaun travelled through Europe to see for himself the main buildings of his time. So he saw Neumann {see planet  (6351)} in Würzburg. Schlaun constructed the Augustusburg Castle in Brühl and several other churches and castles in the style of Westphalian baroque. (M 26765) _ _.
