Why do people visit genocide memorials? This article does not really answer the question but gives some interesting views from visitors, including a couple who made a world tour of genocide memorials. It does touch on some of the important issues faced by curators and visitors though - for example how they should be presented, how recent events should be depicted and if human remains should be displayed.
The IG Farben Haus was not a site of the Holocaust though its victims are remembered there in the form of the Wollheim Memorial and the memorial plaque at the front of the building. In this way the perpetrators and 'Schreibtisch-Täter' are necessarily brought to mind -as it was they, not the killers who were active in the building.
