Josef Mengele was especially interested in identical twins, people with eyes of two different colours (heterochromia iridum), dwarfs, and people with physical abnormalities of which they were born with. Twins were forced to participate weekly examinations and measurements of their physical idiosyncrasy by Mengele or one of his assistants. Some experiments performed by Mengele and his assistants on twins included unnecessary amputation of limbs, intentionally infecting one of the twins with typhus or other diseases, and transfusing the blood of one of the twins into the other. Many of the victims died while undergoing these procedures, a specific number is unknown. Sometimes after an experiment was finished, both twins, mostly children were killed and their bodies dissected and studied. One occasion, Mengele killed fourteen sets of Gypsy twins in one night by himself using a chloroform injection to the heart. He then began to dissect each one and noted each and every …show more content…
He conducted experiments to try and attempt to artificially change a persons eye colour by injecting them with chemicals into the eyes of children. This usually resulted in painful and bad infections of the eyes and in some cases blindness. After a victim would die, he removed their eyes and would nail them onto the wall in his office, most likley for decoration. At one stage 36 children were killed and their eyes modified. A visitor to his surgery said they were of a variety of colours from very pale yellow to bright blue, green and violet. He collected the eyes of his murdered victims, in part to send the eyes as “research material” to colleague Karin Magnussen, a KWI researcher of eye pigmentation. The experiments were carried through to test if the colour of the iris in the eye could be changed colours, most likely to be changed from brown to blue. Through conducting the experiment it was clear that the colour of the iris could be changed but only could be done so through injections of chemicals and dyes directly into the eyes. It also could not be carried out without a toll on the persons eyesight and
