Joseph Montgolfier was the brother of Jacques Montgolfier. Together, they invented the hot air balloon in 1783. He appears in “The Golden Age of Ballooning”, the 40th episode of Monty Python's Flying Circus.
He was married to Antoinette, who was tired of his obsession with balloons. Due to Jacques’ incompetence, a fake Louis XIV manages to steal the hot air balloon plans, breaking Joseph's nose in the process. When he presents them to George III, Joseph confronts him. It is unknown if he makes it back to France. He was portrayed by Terry Jones.
