On a marché sur la Lune
Dr. Patella is a ginger bearded osteopathic doctor who appears briefly in "Destination Moon" and "Explorers on the Moon". His model skeleton is arrested by Thomson and Thompson, and later he attends to an unconscious Captain Haddock after his arrival back on Earth. He also sent a congratulatory telegram to Haddock when (incorrect) news of his engagement to Bianca Castafiore was announced in "The Castafiore Emerald".
