Nazi scientist created a twin-town

The steely hearted "Angel of Death", Josef Mengele, whose mission was to create a master race fit for the Third Reich, was the resident medic at Auschwitz from May 1943 until his flight in the face of the Red Army advance in January 1945. His task was to carry out experiments to discover by what method of genetic quirk twins were produced – and then to artificially increase the Aryan birthrate for his master, Adolf Hitler.

Historians claim Mengele's notorious experiments may have borne fruit. For years scientists have failed to discover why as many as one in five pregnancies in a small Brazilian town have resulted in twins – most of them blond haired and blue eyed. But residents of Candido Godoi now claim that Mengele made repeated visits there in the early 1960s, posing at first as a vet but then offering medical treatment to the women of the town. Shuttling between Argentina, Paraguay and Brazil, he managed to evade justice before his death in 1979, but his dreams of a Nazi master race appeared unfulfilled.
