Constantin Le Paige's secondary education was at Spa and at Liège. He entered the University of Liège to study mathematics in 1869 where he attended lectures by Catalan . After graduating in 1875 he began teaching at the University of Liège. He taught courses on the theory of determinants , which is not surprising since this was Catalan 's speciality, and he also taught higher analysis.

He was appointed professor at the University of Liège in 1882 and remained there the whole of his career, retiring in 1922.

Le Paige worked on the theory of algebraic forms, a topic whose study was initiated by Boole in 1841 and then developed by Cayley , Sylvester , Hermite , Clebsch and Aronhold . In particular Le Paige studied the geometry of algebraic curves and surfaces, building on this earlier work. He is best known for his construction of a cubic surface given by 19 points.

Le Paige studied the generation of plane cubic and quartic curves, developing further Chasles 's work on plane algebraic curves and Steiner 's results on the intersection of two projective pencils.

The history of mathematics was another topic which interested Le Paige. He published Sluze 's correspondence with Pascal , Huygens , Oldenburg and Wallis .

In 1897 Le Paige was appointed director of the Institut d'Astrophysique de Cointe-Sclession. After this he wrote a number of astronomical texts. He also wrote on the history of mathematical notation in Sur l'origine de certains signes d'opération (1891). His interesting history of mathematics Notes pour servir à l'histoire des mathématiques dans l'ancien pays de Liège contains much information on the Belgium astronomer Wendelin.

Le Paige received many honours. He was elected to the Royal Academy of Sciences of Belgium in 1885, to the Royal Society of Sciences of Liège in 1878, to the Royal Society of Bohemia in 1881, to the Royal Academy of Sciences of Lisbon in 1883 and to the Mathematical Society of Amsterdam in 1886.
