Charles Julien Brianchon (19 December 1783 – 29 April 1864) was a French mathematician and chemist.

Life[edit]

He entered into the École Polytechnique in 1804 at the age of eighteen[dubious ], and studied under Monge, graduating first in his class in 1808, after which he took up a career as a lieutenant in Napoleon's artillery. Later, in 1818, Brianchon became a professor in the Artillery School of the Royal Guard at Vincennes.

Work[edit]

Brianchon is best known for his proof of Brianchon's theorem (1810).

Brianchon's book Mémoire sur les lignes du second ordre (Paris, 1817) is available online [1].
