Descartes, Rene


Mathematician and philosopher born in Indre-et-Loire, France (1596-1650). Descartes invented analytical geometry and developed what is now called the Cartesian coordinate system, which describes geometry in term of algebra. He was an influential philosopher as well, famously stating, "Cogito ergo sum" (I think therefore I am).
