Michel Waldschmidt (born June 17, 1946 at Nancy, France) is a French mathematician, specializing in number theory, especially transcendental numbers.
Waldschmidt was educated at Lycée Henri Poincaré[] and the University of Nancy until 1968. In 1972 he defended his thesis, titled Indépendance algébrique de nombres transcendants (Algebraic independence of transcendental numbers) and directed by Jean Fresnel, the University of Bordeaux, where he was research associate of CNRS in 1971–2. He was then a lecturer at Paris-Sud 11 University in 1972–3, then a lecturer at the University of Paris VI (Pierre et Marie Curie), where he is Professor since 1973. Waldschmidt was also a visiting professor at places including the École normale supérieure. He is a member of the Institut de mathématiques de Jussieu[].
Today, Michel Waldschmidt is an expert in the theory of transcendental numbers and diophantine approximations.
He was awarded the Albert Châtelet Prize in 1974, the CNRS Silver Medal in 1978, the Marquet Prize of Academy of Sciences in 1980 and the Special Award of the Hardy–Ramanujan Society in 1986.
From 2001 to 2004 he was president of the Mathematical Society of France. He is a member of several mathematical societies, including the EMS, the AMS and Ramanujan Mathematical Society.
