Voltaire

Pen name of François-Marie Arouet (1694-1778), a French philosopher and writer, the author of Candide. It is not known how Arouet devised his name. He may have reversed the syllables of Airvault, a town where his family owned property; it may have been an anagram of the Latin spelling of his surname Arovet and LI standing for le jeune "the young"; or it may have come from French volontaire "determined".
