The words are Primo Levi's, as was that number. The tattooing of a number on the flesh of the prisoners at Auschwitz was part of the more general process by which the camp authorities tried to deny them their personal identities as individual human beings. To reduce each prisoner to a mere number, deprived of his or her name as well as of all personal tokens that might be a reminder of home, or family, or even just personal idiosyncrasy, was part of the infamy of that place. The documentary Numbered now endeavours to highlight the experience of Holocaust survivors through their relationship to these numbers they still carry.
Häftling: I have learnt that I am Häftling [prisoner]. My number is 174517; we have been baptized, we will carry the tattoo on our left arm until we die.
