2. Bayer/IG Farben
At one point a part of the German pharmaceutical company IG Farben, Bayer is best known for creating aspirin. IG Farben disbanded in 1952, due to controversy over their dealings with Nazis. Farben worked closely with Nazi officials, had Nazis secure chemical plants for them in order to continue production, used slave labor, and worst of all, created Zyklon B, the toxic gas used in the gas chambers. In the 1890’s aspirin was created by two Bayer chemists, Felix Hoffman and Arthur Eichengun. When the Nazi party rose to power, Bayer removed Eichengun’s credit from their records. The reason being that Arthur Eichengun was jewish, and they didn’t want to be associated with him as the war broke out.
