He was a French mathematician and a member of the Académie française (1885).
His main works were in the areas of geometry and complex analysis.
He also investigated orthogonal polynomials (see Laguerre polynomials).
Laguerre's method is a root-finding algorithm tailored to polynomials.
He laid the foundations of a geometry of oriented spheres (Laguerre geometry and Laguerre plane), including the Laguerre transformation or transformation by reciprocal directions.
