Andreas Vesalius
Andreas Vesalius (; 31 December 1514 – 15 October 1564) was a 16th-century Flemish anatomist, physician, and author of one of the most influential books on human anatomy, "De humani corporis fabrica" ("On the Fabric of the Human Body"). Vesalius is often referred to as the founder of modern human anatomy. He was born in Brussels, which was then part of the Habsburg Netherlands. He was professor at the University of Padua and later became Imperial physician at the court of Emperor Charles V.
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.
