François-Marie Arouet (November 21, 1694 - May 30, 1778), known by his nom de plume Voltaire, was a French Enlightenment writer, historian and philosopher famous for his wit, his attacks on the established Catholic Church, and his advocacy of freedom of religion, freedom of expression, and separation of church and state. Voltaire was a versatile writer, producing works in almost every literary form, including plays, poems, novels, essays, and historical and scientific works. He wrote more than 20,000 letters and more than 2,000 books and pamphlets. As a satirical polemicist, he frequently made use of his works to criticize intolerance, religious dogma, and the French institutions of his day. (Click for full Wikipedia article.)
