Louis-Benjamin Francoeur
Louis-Benjamin Francoeur (born August 16, 1773 in Paris , † December 15, 1849 there ) was a French mathematician .
Francoeur came from a well-known family of musicians; his father was temporarily director of the Paris Opera Orchestra. After serving in the French Revolutionary Army, he studied from 1794 to 1797 at the newly founded École polytechnique with Gaspard Monge . After graduating, he wanted to become a military cartographer, but Gaspard de Prony brought him to the École polytechnique as an assistant. For a while he was also formally an artillery officer, but not on active duty. In 1804 he was professor of mathematics at the École polytechnique and in 1805 mathematics teacher at the Lycée Charlemagne. In 1808 he became a professor at the Sorbonne, which he remained until 1845. During the restoration after the end of Napoleon, he lost his post at the École polytechnique and the Lycée Charlemagne (which he kept until 1822), but remained professor at the Sorbonne (Faculté des Sciences in Paris) until 1848, although he suffered from a larynx disease from 1817 forced to be represented.
He wrote numerous textbooks, not only on mathematics, mechanics, geodesy and astronomy (which he had been interested in since the appearance of the Great Comet in 1811 ), but also on botany and was known as the author of a school book on drawing.
In 1842 he became a member of the Académie des Sciences , and he was a member of the academies in Saint Petersburg (1809), Edinburgh , Toulouse, Lisbon and Lyon. The Rue Francoeur in Paris bears his name.
His son Isidore also taught mathematics (at the Collège Chaptal and the École des Beaux-Arts). His widow donated the Prix Francoeur awarded by the Académie des Sciences.
