And Bayer didn't stop the innovation train at Drugging Children Station. They also got into the profitable business of poisoning vermin. IG Farben, Bayer's parent company until it was broken up after the war, bought a firm that invented the cyanide-based pesticide Zyklon B. Unfortunately for, just, everyone, the Nazi definition of "vermin" covered "everyone who isn't Aryan as f**k, especially Jews," and Zyklon B became a major killing instrument of the Holocaust. Bayer apologized for their role in the Holocaust in 1995, and then four years later, a lawsuit was brought alleging that camp inmates were injected with diseases as part of Bayer clinical trials.
While we're in the 1940s, it's probably worth pointing out that Monsanto played a critical role in building the atom bomb. To be specific, they helped make the trigger. And during the Vietnam War, they helped manufacture Agent Orange for the U.S. government. Their website emphatically reminds us that eight other companies also produced Agent Orange, and besides it's probably not that bad anyway, you guys.
Monsanto's buck-passing there is pretty egregious, considering the VA is NOT famous for giving away money and readily admits that a ton of health problems among Vietnam veterans can be traced to Agent Orange. Today, the biggest claim against Monsanto is that 300,000 Indian farmers have committed suicide due to the company's expensive seeds and pesticides driving them to bankruptcy and making them ill.
