Henricus Regius
1598–1679 · Dutch philosopher and physician, advocate of Cartesianism
Henricus Regius (born Hendrik de Roy, also known by the French form Henri Le Roy) was a Dutch philosopher and physician born in Utrecht in 1598 and who died there in 1679. He belongs to the first generation of followers of René Descartes, whose philosophy he defended publicly at a time when it provoked heated debate in the universities of the Dutch Republic.
He studied liberal arts at Franeker and medicine at Groningen, Leiden, and later at Montpellier and Padua. In 1638 he became professor of medicine at the University of Utrecht. From that chair he spread Cartesian natural philosophy, and his textbook Fundamenta Physices served as a teaching manual. He corresponded frequently with Descartes, sharing the aim of explaining natural phenomena in mechanical terms.
His influence was felt above all in teaching. His students included Lambert van Velthuysen, Johannes de Raey, and Johannes van Horne, who carried Cartesianism forward in the Netherlands.
