Michel Eyquem de Montaigne was one of the most influential writers of the French Renaissance. Montaigne is known for popularizing the essay as a literary genre. He became famous for his effortless ability to merge serious intellectual speculation with casual anecdotes and autobiography — and his massive volume Essais contains, to this day, some of the most widely influential essays ever written. Montaigne had a direct influence on writers the world over, from William Shakespeare to René Descartes, from Ralph Waldo Emerson to Stephan Zweig, from Friedrich Nietzsche to Jean-Jacques Rousseau. He was a conservative and earnest Catholic but, as a result of his anti-dogmatic cast of mind, he is considered the father, alongside his contemporary and intimate friend Étienne de La Boétie, of the 'anti-conformist' tradition in French literature.
