|Known for||Laguerre polynomials, Laguerre's method, Laguerre plane|
Edmond Nicolas Laguerre (9 April 1834, Bar-le-Duc - 14 August 1886, Bar-le-Duc) 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.
