Prior to his arrival at Auschwitz, he had published three articles, one of which was his dissertation in the Anthropological Institute at the University of Munich and which was entitled "Racial-Morphological Examination of the Anterior Portion of the Lower Jaw in Four Racial Groups". His medical dissertation, published in 1938, was entitled "Genealogical Studies in the Cases of Cleft Lip-Jaw-Palate". This was a predecessor to his work on genetic abnormalities and indirectly on twins which was to take place at Auschwitz. The third article - entitled "Hereditary Transmission of Fistulae Auris" was published in conjunction with research done on the Lenz-Vershuer principle of "irregular, dominant hereditary process". It appeared in 1928 that Mengele was destined for the academia.
Hitler was obsessed with the idea of the superiority of the “pure” German race, which he called “Aryan,” and with the need for “Lebensraum,” or living space, for that race to expand. In the decade after he was released from prison, Hitler took advantage of the weakness of his rivals to enhance his party’s status and rise from obscurity to power. On January 30, 1933, he was named chancellor of Germany. After President Paul von Hindenburg’s death in 1934, Hitler anointed himself as “Fuhrer,” becoming Germany’s supreme ruler.
^ "War nicht der 'Archipel Gulag' ursprünglicher als 'Auschwitz'? War nicht der 'Klassenmord' der Bolschewiki das logische und faktische Prius des 'Rassenmords' der Nationalsozialisten? Sind Hitlers geheimste Handlungen nicht gerade auch dadurch zu erklären, daß er den 'Rattenkäfig' nicht vergessen hatte? Rührte Auschwitz vielleicht in seinen Ursprüngen aus einer Vergangenheit her, die nicht vergehen wollte?"
The twins were then tattooed and given a number from a special sequence. They were then taken to the twins' barracks where they were required to fill out a form. The form asked for a brief history and basic measurements such as age and height. Many of the twins were too young to fill the form out by themselves so the Zwillingsvater (twin's father) helped them. (This inmate was assigned to the job of taking care of the male twins.)
Though it had ancient roots, Nazi ideology was far from a primitive, medieval throwback - it was capable of appealing to intelligent and sophisticated people. Many high-ranking Nazis had doctoral degrees and early supporters included such eminent people as philosopher Martin Heidegger, theologian Martin Niemoeller, and commander-in-chief of German forces in the First World War, General Erich Ludendorff. Hitler appealed with a powerful vision of a strong, united and 'racially' pure Germany, bolstered by pseudo-scientific ideas that were popular at the time.
