Charles Briot

Charles Auguste Briot (born July 19, 1817 in Saint-Hippolyte , Département Doubs , † September 20, 1882 in Bourg-d'Ault ) was a French mathematician who dealt with function theory.

Life

Briot was the son of a businessman in the tannery industry. After an accident in his childhood he had a stiff arm and concentrated on mathematics according to his inclinations, together with his school friend Jean-Claude Bouquet , whom he was two years ahead of. In 1837 he graduated and taught for a year before taking the exams for the École normal supérieure (ENS) in Paris, which he passed second. He was the first to graduate ( Agrégation ) in 1841. In 1842 he received his doctorate, as did his friend Bouquet in the same year. He then worked as a high school teacher in Orléans before accepting a job at the University of Lyon , as did his friend Bouquet, with whom he worked closely from then on. In 1851 he went to Paris, where he taught at high schools, but also gave courses at the École polytechnique (for which he prepared his students in special courses at high schools) and at the Faculty of Sciences. From 1864 he was a professor at the Sorbonne and at the École normal supérieure (Paris) . In 1867 he was elected a corresponding member of the Göttingen Academy of Sciences .

Briot was known in 19th century France for numerous textbooks, often written together with Bouquet. He worked on elliptical functions ( Recherches sur la théorie des fonctions , 1859) and - inspired by his friend Louis Pasteur - on theoretical physics (ether theories of light in Essai sur la théorie mathématique de la lumière 1864, heat theory in Théorie mécanique de la chaleur 1869). In 1859 he published with Briot Théorie des fonctions doublement périodiques (Mallet-Bachelier) and in 1875 Théorie des fonctions elliptiques (Gauthier-Villars), both widespread textbooks on elliptical functions, often known only briefly as "Briot Bouquet".

Awards

In 1882 he received the Poncelet Prize from the French Académie des Sciences .
