Dobrowolski was 108.
Adam Cyra, a historian at Auschwitz-Birkenau, said Dobrowolski was a member of the Secret Teaching Organization during World War II, providing lessons to students despite a Nazi ban. Dobrowolski, born Oct. 8, 1904, in Wolborz, Poland, was arrested by the Gestapo in June 1942 and sent to Auschwitz, where he was given number 38081, the Polish news agency PAP reported.
He was later sent to Gross-Rosen concentration camp and was freed in 1945.
After the war, he lived in Debno, where he taught in a primary school and later served as director of the local high school, the news agency said.
