IG Farben?

Builder of the nazi crematoriums I beleive

[Alas Babylon!]

Yeah, they manufactured a synthetic rubber plant in Auschwitz, but I think they most famous for manufacturing the Zyklon-B and Sarin gas used to gas concentration camp victims.

Completed in 1930, the IG Farben Building in Frankfurt was seized by the Americans after the war. In 1996 it was transferred to the German government and in 2001 to the University of Frankfurt.
