Aventis
Aventis was formed in 1999, when the French company Rhône-Poulenc S.A. merged with the German corporation Hoechst Marion Roussel, which itself was formed from the 1995 merger of Hoechst AG with Cassella, Roussel Uclaf, and Marion Merrell Dow. Hoechst AG, the majority partner at the time in Hoechst Marion Roussel, was itself a merger of two of the three forcibly separated subsidiaries of IG Farben, exploiter of Auschwitz slave labor and supplier of Zyklon B during The Holocaust. The merged company was based in Schiltigheim, near Strasbourg, France.
