The Prix Audin was awarded to Michel Lazard in 1958, marking him as the inaugural recipient of an honor established to commemorate the life of mathematician Maurice Audin. Lazard spent his career refining the understanding of algebraic structures, specifically contributing to the study of Lie groups and formal group laws during the mid-20th century.
Academic Foundations and Doctoral Research
Born in 1924 within the 4th arrondissement of Paris, Lazard pursued his advanced studies at the University of Paris–Sorbonne. His doctoral training concluded in 1954 under the supervision of Albert Châtelet. The resulting thesis, titled Sur les groupes nilpotents et les anneaux de Lie, established the trajectory for his future research into p-adic analysis and formal groups.

Lazard’s mathematical output included several major innovations. He developed the classification of p-adic Lie groups, proving that every such group functions as a closed subgroup of GLn(Zp). Furthermore, his work on commutative formal groups provided the basis for the universal formal group law coefficient ring, which he identified as a polynomial ring. He also introduced the concept of analyseurs, a precursor to what is now known as operads.
Influence and Legacy
The research conducted by Lazard experienced a significant resurgence in the late 20th century through the work of Daniel Quillen. By demonstrating that the ring Lazard used to categorize formal group laws was isomorphic to a fundamental ring in topology, Quillen facilitated the development of chromatic homotopy theory. Additionally, Lazard’s treatise on one-dimensional formal groups became foundational for the study of p-divisible groups.
Professional Recognition
Throughout his tenure as a professor at the University of Poitiers and the University of Paris 7, Lazard’s work garnered formal acknowledgment from the mathematical community. Beyond his recognition with the Prix Audin in 1958, the Académie des Sciences bestowed upon him the Poncelet Prize in 1972 in recognition of his significant contributions to the field of algebra.
