Louis I, Duke of Orléans
The Chronique de la Pucelle or Chronique de Cousinot was composed by Guillaume Cousinot (1400-1484), seigneur de Montreuil, the son of Guillaume Cousinot (d. circa 1442) who was chancellor to Louis I, Duke of Orléans. The younger Cousinot is a major contemporary source for the episode of the Hundred Years' War that featured the career of Joan of Arc.
