Before World War II, Kurt (Fritz)[1] Küttner worked for many years as a warden in the German police. During Operation Reinhard in occupied Poland he was in charge of the lower camp of Treblinka II Totenlager, where he became one of the most feared and hated SS officers. He would follow people around, stop them and search for money, pictures or any family mementos that the Sonderkommando prisoners would try to hide on their person.
