Harry Haft survived through his skills as a boxer for the entertainment of the Nazis in Auschwitz. Others imprisoned at the camp—including Benjamin Jacobs, a dentist—have mentioned in their testimonies that their professional usefulness to their captors may have saved their lives. Besides boxing, another form of entertainment for the Nazis at Auschwitz was the camp orchestra. The Visual History Archive has the testimonies of several musicians who recount their experiences playing in the orchestra.
