Flemish mathematicians

Godfried Wendelen or Govaert Wendelen, Latinized Godefridus Wendelinus, or sometimes Vendelinus and in French-language sources referred to as Godefroy Wendelin (6 June 1580 – 24 October 1667) was an astronomer and Catholic priest sometimes referred to as the Ptolemy of his time. He was a supporter of Copernican heliocentrism, the astronomical model which positioned the sun at the center of the universe, with earth and the other planets orbiting around it. He made more accurate measurements of the distance to the sun as previously made by the ancient Greek astronomer Aristarchus of Samos. He is considered by some as a precursor of Kepler and Newton. He stayed in the Provence where he met Peiresc with whom he remained in contact throughout his life. The crater Vendelinus on the Moon is named after him.

Theodorus Moretus, also known as Theodor or Theodore Moretus (1602–1667) was a Flemish Jesuit priest who was also a mathematician, geometer, theologian and philosopher. He spent most of his working life in Prague and Breslau (now Wroclaw) where he taught philosophy, theology and mathematics. He published a number of treatises on these three subjects and also on physics and music theory.

Simon Stevin (1548–1620), sometimes called Stevinus, was a Flemish mathematician, scientist and music theorist. He made various contributions in many areas of science and engineering, both theoretical and practical. He also translated various mathematical terms into Dutch, making it one of the few European languages in which the word for mathematics, wiskunde (wis and kunde, i.e., "the knowledge of what is certain"), was not a loanword from Greek but a calque via Latin. He also replaced the word chemie, the Dutch for chemistry, by scheikunde ("the art of separating"), made in analogy with wiskunde.

Cornelis de Schepper, Cornelis Duplicius de Schepper or Cornelius de Schepper (1503?-1555) was a Flemish mathematician, counselor and ambassador for the Holy Roman Emperor Charles V, Ferdinand I of Austria and Mary of Hungary, governor of the Netherlands. He is also known by his Latin name Scepperus.

Johannes Stadius or Estadius (Dutch: Jan Van Ostaeyen; French: Jean Stade) (ca. 1 May 1527 – 17 June 1579), was a Flemish astronomer, astrologer, and mathematician. He was one of the important late 16th-century makers of ephemerides, which gave the positions of astronomical objects in the sky at a given time or times.

Father Ferdinand Verbiest (9 October 1623 – 28 January 1688) was a Flemish Jesuit missionary in China during the Qing dynasty. He was born in Pittem near Tielt in the County of Flanders (now part of Belgium). He is known as Nan Huairen (南懷仁) in Chinese. He was an accomplished mathematician and astronomer and proved to the court of the Kangxi Emperor that European astronomy was more accurate than Chinese astronomy. He then corrected the Chinese calendar and was later asked to rebuild and re-equip the Beijing Ancient Observatory, being given the role of Head of the Mathematical Board and Director of the Observatory.

Jean-Charles della Faille (Dutch: Jan-Karel della Faille, Spanish: Juan Carlos della Faille), born in Antwerp, 1 March 1597 and died in Barcelona, 4 November 1652, was a Flemish Jesuit priest from Brabant, and a mathematician of repute.

Jan Vaerman (1653–1731) was a Flemish mathematician.

Michiel Coignet (also Quignet, Cognet or Connette in Italian) (1549 in Antwerp – 24 December 1623 in Antwerp) was a Flemish polymath who made significant contributions to various disciplines including cosmography, mathematics, navigation and cartography. He also built new and improved scientific instruments and made military engineering designs.
