About 50m from the southwest corner of the IG-Farbenhaus building (to the left as you approach the main entrance) stands the Wollheim Memorial in a little pavilion marked ‘107984’ (Norbert Wollheim’s prisoner number). Inside you can watch 24 masterfully done video testimonials, a few in English, by survivors of IG Farben’s corporate slave-labour camp, Buna/Monowitz (Auschwitz III). IG-Farben slave labourers who lived to write about their experiences include Primo Levi and Elie Wiesel.
