How did the findings about Keller and his wife explain the sort of person he was? Explain.

Paul eventually learns that Keller's Jewish wife, Mathilde, and his son, Eric, were both imprisoned and killed in a concentration camp. Although Keller is not Jewish, he registers as a Jew after his wife and son's capture and is also sent to a concentration camp, where everyone believes he died. I think he is always dealing with the hurt and pain of his past. His eccentricities are coping mechanisms that have become ingrained in his personality.
