Claude Buffier, Polish-French historian and philosopher (d. 1737)
Claude Buffier (25 May 1661 – 17 May 1737), French philosopher, historian and teacher, was born in Poland of French parents, who returned to France and settled in Rouen soon after his birth.

He was educated at the Jesuit college there, and he was received into the Order at the age of nineteen. A dispute with the archbishop compelled him to leave Rouen. After a short stay in Rome, he returned to Paris to the college of the Jesuits, where he spent the rest of his life. He seems to have been a good teacher and lucid expositor.
