John Demjanjuk, was a Trawniki and Nazi camp guard at Sobibor extermination camp, Majdanek, and Flossenbürg. Demjanjuk became the center of global media attention in the 1980s, when he was tried and convicted in Israel after being identified as "Ivan the Terrible", a notoriously cruel watchman at Treblinka extermination camp. Demjanjuk was sentenced to death by hanging in 1988. In 1993, the verdict was overturned. Shortly before his death, he was tried and convicted in the Federal Republic of Germany as an accessory to the 28,060 murders that occurred during his service at Sobibor.
Born in Soviet Ukraine, Demjanjuk was conscripted into the Red Army in 1940. He fought in World War II and was taken prisoner by the Germans in spring 1942, becoming a Trawniki collaborator.
