Auschwitz main gate bearing the motto 'Arbeit macht frei' (Work Brings Freedom).

"Work in prison is not merely an efficient corrective, in the best sense of the word, in that it encourages the prisoners to discipline themselves and thus makes them better able to withstand the demoralising effect of their confinement. It is also a means of training for those prisoners who are fundamentally unstable and who need to learn the meaning of endurance and perserverence. The beneficient influence of work can draw many prisoners away from a life of crime. Only thus can the slogan 'Work Brings freedom' be understood."
Rudolf Höss, commandant of Auschwitz 1940 -1943
