Klaus Braun lived in Strausberg during the Nazi regime in Germany. Klaus' father was an SS engineer at Auschwitz who built the camp's crematoria, and Klaus himself was a member of the Hitler Youth from 1941 to 1943. After the Nazi regime fell at the end of World War II, Klaus evaded discovery and arrest by forging the false identity of Abraham Klein, a Jewish survivor of Auschwitz, and fled to America. There, Klaus became a clockmaker and had a Jewish son, David, and he hid and buried the truth about who he really was and what he had done for almost 60 years, until the present day.
