Anatomy
Andreas Vesalius (1514–1564) (Latinized from Andries van Wezel), professor of anatomy at the University of Padua, is considered the founder of modern human anatomy. Originally from Brabant, Vesalius published the influential book "De humani corporis fabrica" ("the structure of the human body"), a large format book in seven volumes, in 1543. The accurate and intricately detailed illustrations, often in allegorical poses against Italianate landscapes, are thought to have been made by the artist Jan van Calcar, a pupil of Titian.
Lorenz Böhler
Böhler is most notable as one of the creators—or even the creator—of modern accident surgery. He was the head of the AUVA-Hospital in Vienna, Brigittenau, that was later named after him: Lorenz-Böhler-Unfallkrankenhaus. This hospital was an international model during his time as the leading surgeon there. 
In radiology, the measurement of "Böhler's angle" on a foot X-ray can help detect fractures of the calcaneus.
