Andreas Tacquet


Belgium (1612–1660)
Andreas Tacquet went to a Jesuit college for his higher education and joined the Jesuit order in 1629. The same year, he began studying at Malines, Belgium. Then, partway through 1631, he went to Louvain and continued his studies. He studied mathematics under William Boalmans, who had been taught by Gregorius Saint Vincent (1). He also studied logic and physics.

From 1634 to 1639, Tacquet taught at Jesuit colleges, and then from 1640 to 1644, he studied theology at Louvean. This was followed by a year or so of teaching math at Louvean. Then, in November 1646, he took his vows and continued to teach math (1).

He published several works, and was known for "great clarity" in his writing (3). His works included Cylindrieorum et annularium, which has some original theorems on cylinders and rings; Elementara geometriae, a well organized paraphrase of parts of Euclid and Archimedes; and a posthumously published work called Opera mathematica (1). The final book, published in 1669, was described by Henry Oldenburg as ‘one of the best books ever written in Mathematics (2), and "contained works on astronomy, spherical trigonometry, practical geometry, and fortification” (3).

Tacquet helped to pave the way for Calculus. Previously people had thought of lines as being composed of points. He introduced the idea that a moving point could generate a line -- or a curve. This, and other ideas, influenced the thinking of Pascal and his contemporaries, and acted as a foundation for future progress (3).

Tacquet was a “brilliant mathematician of international repute.” His books were frequently reprinted and there were several Italian and English editions (1, 2). The Elementara geometriae was one of several math textbooks that he wrote for students in his math class. (3).
