The Evolution of Medical Ethics

Twin Studies

Twin Studies

Twin studies were conducted by Josef Mengele at Auschwitz .

Josef Mengele had a strange fascination with twins, and spent his entire time at Auschwitz studying the twins. Often times his findings or his experiments had very little justification and were conducted solely for Mengele's pleasure.

Mengele would systematically document measurements of the twins, often comparing them. He would also test the effects of various drugs and poisons on one twin and use the other twin as a "control" group in order to make his experiments pseudoscientific. After these experiments he would kill both of the twins in order to dissect and compare the bodies.

Mengele tried to sew together two children together in an attempt to create Siamese twins. The hands of the children became badly infected where the veins were sected together.

These are just a few examples of the atrocities committed by Josef Mengele. Of over 1,500 pairs of twins, only about 200 of these twins survived Mengele and the war.

One twin recalls the death of his brother:

"Dr. Mengele had always been more interested in Tibi. I am not sure why - perhaps because he was the older twin. Mengele made several operations on Tibi. One surgery on his spine left my brother paralyzed. He could not walk anymore. Then they took out his sexual organs. After the fourth operation, I did not see Tibi anymore. I cannot tell you how I felt. It is impossible to put into words how I felt. They had taken away my father, my mother, my two older brothers - and now, my twin ..."

Eva Mozes-Kor was a Mengele Twin. She was luckily a "control" subject.
Her sister survived the war, but died due to complications from
the experiments Mengele performed.
