===Medical experiments===
Staff of the [[Bayer]] group at IG Farben conducted medical experiments on concentration-camp inmates at Auschwitz and at the [[Mauthausen-Gusen concentration camp complex|Mauthausen concentration camp]].{{sfn|Lifton|Hackett|1998|p=310}}<ref name="Other doctor-perpetrators"/> 
At Auschwitz they were led by Bayer employee [[Helmuth Vetter]], an Auschwitz camp physician and SS captain, and Auschwitz physicians [[Friedrich Entress]] and [[Eduard Wirths]]. Most of the experiments were conducted in Birkenau in Block 20, the women's camp hospital. The patients were suffering from, and in many cases had been deliberately infected with, [[typhoid]], [[tuberculosis]], [[diphtheria]] and other diseases, then were given preparations named Rutenol, Periston, B-1012, B-1034, B-1036, 3582 and P-111. According to prisoner-physicians who witnessed the experiments, after being given the drugs the women would experience circulation problems, bloody vomiting, and painful diarrhea "containing fragments of mucus membrane". Of the 50 typhoid sufferers given 3852, 15 died; 40 of the 75 tuberculosis patients given Rutenol died.{{sfn|Strzelecka|2000|p=362}}

For one experiment, which tested an anaesthetic, Bayer had 150 women sent from Auschwitz to its own facility. They paid RM 150 per woman, all of whom died as a result of the research; the camp had asked for RM 200 per person, but Bayer had said that was too high.<ref>{{harvnb|Strzelecka|2000|p=363}}; {{harvnb|Rees|2006|p=179}}; {{harvnb|Jacobs|2017|pp=312–314}}.{{pb}}{{cite news |last1=Worthington |first1=Daryl |title=IG Farben Opens Factory at Auschwitz |url=https://www.newhistorian.com/ig-farben-opens-factory-at-auschwitz/3822/ |work=New Historian |date=20 May 2015 |archive-url=https://web.archive.org/web/20150522040626/https://www.newhistorian.com/ig-farben-opens-factory-at-auschwitz/3822/ |archive-date=22 May 2015}}</ref> A Bayer employee wrote to [[Rudolf Höss]], the Auschwitz commandant: "The transport of 150 women arrived in good condition. However, we were unable to obtain conclusive results because they died during the experiments. We would kindly request that you send us another group of women to the same number and at the same price."<ref>{{harvnb|Strzelecka|2000|p=363}}, citing
