Captain Nemo is a character created by the French novelist Jules Verne (1828–1905). Nemo appears in two of Verne's science-fiction books, Twenty Thousand Leagues Under the Seas (1870) and The Mysterious Island (1875). He also makes a brief appearance in a play written by Verne with the collaboration of Adolphe d'Ennery, Journey Through the Impossible (1882).

Jules Gabriel Verne was a French novelist, poet, and playwright. His collaboration with the publisher Pierre-Jules Hetzel led to the creation of the Voyages extraordinaires, a series of bestselling adventure novels including Journey to the Center of the Earth (1864), Twenty Thousand Leagues Under the Seas (1870), and Around the World in Eighty Days (1872). His novels, always well documented, are generally set in the second half of the 19th century, taking into account the technological advances of the time.
