Charles Auguste Briot, French mathematician, was born on July 19, 1817 in St. Hippolyte. He was responsible for important contributions in analysis, heat, light and electricity. Despite losing his arm movement due to a childhood accident, he never gave up on being a teacher.
In 1838, a year after his arrival in Paris, he began to study at Ecole Normale Supérieure (1838), where he obtained a doctorate (1842) defending work on the orbit of a solid body around a fixed point. Became a teacher at Orléans Lycée and later at the University of Lyon, where he reunited with his childhood friend Claude Bouquet, with whom he did an important job in analysis.
In 1851, he returned to Paris, where he taught in various high schools and was a substitute teacher in several higher courses. He taught calculus, mechanics and astronomy, especially in Ecole Polytechnique and on Faculty of Sciences. In the following decade, in 1864, he became professor of Sorbonne and from Ecole Normale Supérieure. Briot has written many important books in the field of teaching, and has received many honors for his work.
He died on September 20, 1882, in Bourg-d'Ault, France.
