Evil Science Experiments: The Nazis

Almost any list of “X Most Evil Whatevers” is pretty much obligated to have a bunch of Nazis on it, even if it’s just a list of evil cupcake recipes. In non-consensual medical experiments of dubious scientific value, however, the Nazis really outdid themselves. Never has so much that was so bad been done for the enlightenment of so few for such little identifiable purpose.

At Auschwitz, Dr. Josef Mengele injected dye into the eyes of children to see if he could permanently change their color. He also famously tried to create conjoined twins by stitching his patients together.

Thank your lucky stars it didn’t work, because can you imagine if the Third Reich had perfected Siamese twin technology in time to win the war? Their elite Dopplesoldaten would have been unstoppable!

In 1942, Nazi doctors in Baranowicze, Poland strapped a young boy into a chair and repeatedly hit his head with a mechanized hammer.. It turns out that one out of one test subjects react negatively to this.

At the Ravensbrück women’s camp, the effectiveness of sulfonamide, a synthetic antibiotic, was tested on prisoners. Their arms and legs were gashed and blood supply was cut off to simulate battle wounds. Then the wounds were treated with bacteria and—five will get you ten—rubbed with ground glass because why not?

The Nazi doctors who didn’t escape to South America were put on trial after the war. Some, mostly administrators, were acquitted. The guilty were given sentences ranging from ten years to death by hanging. So…happy ending?
