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.
