Kajetan "Kai" Mühlmann was an Austrian art historian who was an officer in the SS and played a major role in the expropriation of art by the Nazis, particularly in Poland and the Netherlands. He worked with Arthur Seyss-Inquart in the initial Nazi government in Vienna following the Anschluss, in the General Government and in The Hague where he headed an organisation known as the Dienststelle Mühlmann which functioned as a clearing house for art expropriated in the occupied Netherlands. He has been characterised as one of the greatest art thieves among the Nazis, and possibly ever.
