Carl von Rokitansky, Bohemian physician, pathologist, and politician (born 1804)

Baron Carl von Rokitansky was a Czech-born Austrian physician, pathologist, humanist philosopher and liberal politician, founder of the Viennese School of Medicine of the 19th century. He was the founder of science-based diagnostics, connecting clinical with pathological results in a feedback loop that is standard practice today but was daring in Rokitansky's day.
