Louis XIV was a man posing as the French king Louis XIV, managing to fool everyone despite his strong Scottish accent. He appears in “The Golden Age of Ballooning”, the 40th episode of Monty Python's Flying Circus. He was portrayed by Michael Palin.
Louis and his gang go to Joseph and Jacques Montgolfier’s house and steals their hot air balloon plans, after forgetting which number Louis he was. He then tried to sell them to George III, who insisted he stay for dinner to discuss his troops in America in return for buying the plans.
