René Descartes was a French philosopher, mathematician, and writer. Descartes is often called the Father of Modern Philosophy, and much of early Western philosophy is a response to his writings. Descartes writing are still studied closely to this day.

Descartes was also influential in mathematics; the Cartesian coordinate system — allowing reference to a point in space as a set of numbers, and allowing algebraic equations to be expressed as geometric shapes in a two-dimensional coordinate system (and conversely, shapes to be described as equations) — was named after him.

Descartes was also one of the key figures in the Scientific Revolution and has been described as an example of genius.
