“In 1942, somebody came back to our village from Treblinka. His name was Spivak, he escaped by hiding in a wagon full of clothing. He described what was going on there, and said he got crazy from what he had seen. We didn’t believe him, we didn’t believe in the crematoria. We thought he was a madman telling an unbelievable tale. How could such a thing be happening in our world, our modern world?”
