Graetschus joined the SS in 1935 and the Nazi Party in 1936. He served at Bernburg Euthanasia Centre and Treblinka extermination camp before being posted to Sobibor in August 1942. He succeeded Erich Lachmann as commander of the approximately 200 Ukrainian Trawniki guards at Sobibor.[2][3] He was known for his brutality and his murderous nature. At the very beginning Siegfried Graetschus transformed a confiscated post car into a mobile gas chamber. The vehicle was used for some time to murder people with disabilities and the mentally ill who were searched for in nearby villages. Finally it was decided not to use it more widely and to use stationary gas chambers instead.
Graetschus was killed during the prisoner revolt at Sobibor. While sources agree that he was killed in the shoemaker's barracks with an axe to the head, they differ as to whether the fatal blow was struck by Yehuda Lerner, a Varsovian Jew, or by Arkady Wajspapir, a Jewish Russian Red Army soldier.[4][5][6]
