Figure 1A: A 1928 portrait of Hans Haustein (b. 1894) by Christian Schad. Haustein was a leading German dermatologist researching archival documents on the early history of Syphilis. One of his main conclusions was that syphilis arrived on the European public health arena after the discovery of the Americas. He was of Jewish heritage and socialized in Berlin’s left-leaning cultural circles. There are conflicting accounts of his tragic fate after being arrested and harassed by the Gestapo in 1933 [40]. Image of Hans Haustein reproduced with permission from Museo Thyssen-Bornemisza, Madrid.
B: A woodcut portrait of Conrad Gessner (1516–1565) often printed on the initial pages of his books. Gessner was the principal physician of Zurich and one of the best-known naturalists and physicians in 16th century Europe. He died of the Plague. The year 2016 marks the 500th anniversary of his birth.
