Marquis de Sade (Count Donatien-Alphonse-François de Sade)
Born a rich nobleman, Marquis being his title rather than his birth name, De Sade gradually became a decadent libertine among the French society of Louis XVI. A liberally educated iconoclast, he wrote prose and verse, and specialized in testing the limits of decency, breaking tabboos and shocking the aristocracy, often with sordid details drawn from real life. He was thought to have committed much of the perversions and debauchery he had written about. He was incarcerated in an asylum shortly before the French Revolution. Read more... uneventful calm. De Sade has been portrayed in movie and TV by Daniel Auteuil, Stuart Devenie, Keir Dullea, Robert Englund, Klaus Kinski, Patrick Magee, Nick Mancuso, Geoffrey Rush, Brother Theodore, and Conrad Veidt.
