Dr. Horst Schumann
Dr. Horst Schumann was famous for some of his experiments. These experiments would be scary and inhumane. However, he didn't care about his test subjects. Some things that he did included injecting people with typhus (a bacterial disease spread by lice or fleas) and trying to cure them. He was successful. He also had a device that was inserted into a patient through the rectum to simulate the prostate and produce ejaculation.
