Theodorus Moretus

Theodorus Moretus, also known as Theodor or Theodore Moretus, was a Flemish Jesuit priest, mathematician, geometer, theologian and philosopher, born in Antwerp in 1602 and dead in 1667. His mother was a daughter of Christophe Plantin, founder of the Plantin Press, and his father was a brother of Jan Moretus and a diamond trader. He studied mathematics at the Jesuit school in Antwerp founded by François d'Aguilon, joined the Jesuits at Mechelen in 1618 and studied at Leuven, where Gregorius van St-Vincent arranged for him to send mathematical dissertations to Christoph Grienberger in Rome. From 1631 he joined van St-Vincent in Prague, and he spent most of his working life in Prague and Breslau, teaching philosophy, theology and mathematics. He wrote the first mathematical dissertation defended in the Clementinum, and published treatises on mathematics, theology, physics and music theory.
