History of Sorts

David Olère  was a  Jewish Polish-born French painter and sculptor best known for his explicit drawings and paintings based on his experiences as a Jewish Sonderkommando inmate at Auschwitz-Birkenau concentration camp.

He began to draw at Auschwitz-Birkenau during the last days of the camp, when the SS became less attentive. His work has an invaluable as evidence  documentary: there are no photos of what happened in the gas chambers and crematoria

Below are just some of his paintings. I believe they speak for themselves.
