Chasles, Michel

[shahl]

(1793--1880)

Mathematician, born in Epernon, NC France. He entered the Ecole Polytechnique in 1812, and became a military engineer, but resigned to devote himself to mathematics, becoming professor of geometry at the Sorbonne in 1846. He greatly developed synthetic projective geometry by means of cross-ratio and homographies without the use of co-ordinates.
