French philosopher, mathematician and writer who spent most of his life in the Dutch Republic. 
He has been dubbed the father of modern philosophy, and much subsequent Western philosophy is a response to his writings, which are studied closely to this day.  In particular, his Meditationes de Prima Philosophia / Meditations on First Philosophy (1641) continues to be a standard text at many Universities. His best known philosophical statement is Cogito ergo sum / Je pense, donc je suis / I think, therefore I am.
He died in Stockholm and was interred in Adolf Fredriks kyrka but in 1666 his remains were taken to France and buried in the Saint-Étienne-du-Mont. His remains were again transferred in 1819 to the Abbey of Saint-Germain-des-Prés, missing a finger and the skull.
