Bayer
founded 1863
From a plant beside Auschwitz to HIV-tainted blood — and then it bought Monsanto's record too.
Bayer arrived with a record of its own before it ever bought Monsanto. It was one of six firms merged in 1925 to create IG Farben, the German chemical cartel tied to a plant beside Auschwitz; it later shipped HIV-tainted blood products abroad. Then it paid about $63 billion for Monsanto and absorbed that record too.
