Biography
He was born in Vise, Belgium and studied at the University of Leuven (1638–1642) and received a master degree in law from the University of Rome, La Sapienza in 1643. There he also studied several languages, mathematics and astronomy. Aside from mathematics he also produced works on astronomy, physics, natural history, general history and theological subjects related to his work in the Church.
He became a canon of the Catholic church in 1650, soon after which he became canon of Liège. In 1666 he took a new position as abbot of Amay. While in those positions, he maintained correspondence with Blaise Pascal, Christiaan Huygens, John Wallis, and Michelangelo Ricci. He was apppointed Chancellor of Liege and Counsellor and Chancellor to Prince Maximilian-Henry of Bavaria.
He was elected a Fellow of the Royal Society in 1674 [1].
He died in Liège.
Mathematical contributions
He found for the subtangent of a curve
- f(x, y) = 0
an expression equivalent to
He also wrote numerous tracts, and in particular discussed at some length spirals and points of inflexion. The Conchoid of de Sluze is named after him. He is described by John Wallis in his Algebra as "a very accurate and ingenious person." Several of his works were included in the Transactions of the Royal Society, e.g. his method of drawing tangents to geometrical curves.
