Michael Servetus (1511-1553) spent his childhood living in Villanova, Spain, before studying law at the University of Toulouse, where he developed an interest in theology. He entered the service of Juan de Quintana, a Franciscan friar and doctor of the University of Paris, and studied medicine in Paris during the 1530s. He was a pioneer physician, who was the first person to write on the pulmonary circulation of blood. However, his religious beliefs provoked controversy, and he was burned at the stake on 27 October 1553 by the Reform Protestants in Geneva for his criticism of the doctrine of the Trinity and his opposition to infant baptism.
Theodor Ludwig Lau (1670-1740) was a German lawyer and philosopher.
