Beginning in 1941, a number of physicians and scientists carried out a varied program of medical experimentation on prisoners at Buchenwald in special barracks in the northern part of the main camp. Medical experiments aimed at testing the efficacy of vaccines and treatments against contagious diseases such as typhus, typhoid, cholera, and diphtheria resulted in hundreds of deaths. In 1944, Danish physician Dr. Carl Vaernet began a series of experiments that he claimed would "cure" homosexual inmates through hormonal transplants.
