Michael Servetus was the first European to correctly describe the function of pulmonary circulation, the portion of the human circulatory system that interacts with the lungs. He described his view of it in his work "Christianismi Restitutio" in 1553. He is best known for his contributions to the history of medicine, but he was also accomplished in astronomy, geography, meteorology, jurisprudence, translation, poetry, mathematics and the scholarly study of the Bible in its original languages. He developed a heterodox view of the Trinity and Christology during the Protestant Reformation and was executed as a heretic.
