M. (Jean Claude) Bouquet

Born in Morteau, France, on September 7, 1819, Jean-Claude Bouquet came from a farming family and studied at the École Normale Supérieure and the University of Paris. He earned degrees in mathematics and physics and completed a doctorate on the variation of double integrals early in his career.

Bouquet taught in Marseille, Lyon, and later at some of Paris's best-known schools, including Lycée Condorcet and Lycée Louis-le-Grand. He also held posts connected with the École Normale Supérieure, the École Polytechnique, and the Sorbonne, where he succeeded Joseph-Alfred Serret in differential and integral calculus.

In mathematics, Bouquet is closely associated with Charles Briot, with whom he worked on differential equations, elliptic functions, and doubly periodic functions. He was elected to the Académie des sciences in 1875, and his name remains attached to the Briot-Bouquet equation, a lasting sign of his place in 19th-century French mathematics.
