In Jules Verne’s novel *Twenty Thousand Leagues Under the Seas*, published in installments in 1869–1870, the *Nautilus* is Captain Nemo’s fictional electric submarine. Verne did not present its diving equipment as his own invention: Nemo uses the real Rouquayrol–Denayrouze apparatus, adapted for the novel. Decades later, the first U.S. nuclear-powered submarine was named USS *Nautilus* after the vessel in Verne’s story, but this does not mean modern submarines descended from Verne’s fiction.
