Augustin Filon
Pierre Marie Augustin Filon (1841–1916) was a French man of letters.
The son of the historian Charles Auguste Désiré Filon, he was born in Paris. Educated at the École normale, he lectured for some years in the Lycées of Nice and Grenoble. In October 1867 Duruy, then the French minister of education, appoined him tutor to the Prince Imperial. Upon the fall of the Second French Empire, the Prince Imperial was exiled to Chislehurst, Kent, accompanied by Filon, who settled in England with his family. He also wrote on English subjects, chiefly under the pseudonym of Pierre Sandrié.
His only child was the distinguished applied mathematician Louis Napoleon George Filon, who worked with Karl Pearson.
