Michel Lazard

Michel Paul Lazard (5 December 1924 – 23 December 1985) was a French mathematician who worked in the theory of Lie groups in the context of p-adic analysis. His work took on a life of its own in the hands of Daniel Quillen in the late 20th century. Quillen's discovery, that a ring Lazard used to classify formal group laws was isomorphic to an important ring in topology, lead to the subject of chromatic homotopy theory.

Lazard's self contained treatise on one-dimensional formal groups also birthed the field of p-divisible groups.
