Józef Andrzej Szeryński (born Josef Szynkman] was a Jewish police-colonel in interwar Poland, inspector for the Lublin district and later – during the Second World War – a commander of the Jewish Ghetto Police in Warsaw with recommendation from Adam Czerniaków. Szeryński was arrested by the Gestapo on May 1, 1942 for smuggling furs out of the Warsaw Ghetto for personal gain. He was released on the condition of leading the deportation action to Treblinka extermination camp in July 1942. The very next month Jewish underground attempted to assassinate him, unsuccessfully. He remained at the helm of the Ghetto Police until the end of the Grossaktion Warschau which claimed the lives of over 254,000 Ghetto inmates, men, women and children.
