The oldest known survivor of the Auschwitz concentration camp - a teacher who gave lessons in defiance of his native Poland's Nazi occupiers - has died at the age of 108, an official said Monday. Antoni Dobrowolski died Sunday in the northwestern Polish town of Debno, according to Jaroslaw Mensfelt, a spokesman at the Auschwitz-Birkenau state museum. After invading Poland in 1939, sparking World War II, the Germans banned anything beyond four years of elementary education in a bid to crush Polish culture and the country's intelligentsia. The Germans considered the Poles inferior beings, and the education policy was part of a plan to use Poles as a "slave race."

Dobrowolski was among the Poles engaged in the underground effort, and he was arrested by the Gestapo and sent to Auschwitz in June 1942. "Auschwitz was worse than Dante's hell," he recalled in a video made when he was 103. Dobrowolski, who was born Oct. 8, 1904 in Wolborz, Poland, was later moved to the concentration camps of Gross-Rosen and Sachsenhausen, according to the Auschwitz memorial museum in southern Poland. After the war, he moved to Debno, where he worked as a Polish-language teacher and as principal at an elementary school and later at a high school for many years. He will be buried in Debno on Wednesday. At least 1.1 million people were killed by the Germans at the Auschwitz-Birkenau camp. Most of the victims were Jews, but many non-Jewish Poles, Roma and others were also killed there.
