Karin Magnussen

She is known for her 1936 publication Race and Population Policy Tools and her studies of heterochromia iridis (different-colored eyes) using iris specimens, supplied by Josef Mengele, from Auschwitz concentration camp victims.

Magnussen joined the National Socialist German Students' League (NSDStB) while she was still an undergraduate in college.

She was first and later second in her state examinations for a high school teaching position; inter alia in biology in 1936.

She possibly modeled herself after "...the biologist Agnes Bluhm, who worked at the Kaiser-Wilhelm-Institut fur Biologie and wrote "Die rassenhygienischen Aufgaben des weiblichen Arztes", Berlin, 1934, and who unhesitatingly supported Hitler's regime."

After the end of the Second World War, in the Soviet zone of occupation, it appeared on the list of prohibited literature.

The current war must therefore be also about the repression of the black danger in the West and the elimination of the Bolshevik threat in the East, which still resolves a racial problem in Europe, which all States are more or less interested in: the Jewish question.

Also the Jew who enjoys life as a host in our country, is our enemy, even if he does not actively engage with weapons in this fight.

…From the European point of view, the Jewish question is resolved in that the emigrant Jews do the thinking for the leaders in the other States.

We have seen that these emigrants are only troublesome and set up the peoples against each other.Having received a scholarship, Magnussen was suspended in fall 1941 from her teaching profession and moved to the Kaiser Wilhelm Institute of Anthropology, Human Heredity, and Eugenics (KWI-A), in Berlin-Dahlem.

Magnussen used the scientific method to lead her to the conclusion that the eye is not only genetically, but also hormonally, determined.

According to a statement by Magnussen, Mengele dealt, among other things, with the eyes of these Sinti family using hormonal substances.

In the event of death of the prisoners, Mengele pledged to Magnussen to give her the eyes of the victims for further research and evaluation.

[13] The Hungarian prisoner pathologist Miklós Nyiszli noted after the autopsy of Sinti twins that they had been killed, not due to illness, but because of a chloroform injection to the heart.

[16] She was entangled by her cooperation with Mengele and the supply of "human material", and mired deep in concentration camp crimes, but she claimed to know nothing about them.
