Gilles de Retz
Gilles de Retz (1404-40) was Marshal of France and a war hero, who fought beside Jean d’Arc at the battle of Orleans. A patron of music and arts, he retired early from warfare, returned to his vast estates. Apparently he spent his time kidnapping and violating young boys. His arrest and trial revealed his disgusting pastimes. He was convicted of murdering more than 100. His wealth and position gave him celebrity and he is supposedly the original model for Blue Beard.
