Adolphe d'Ennery in the context of The Impossible Voyage

Michael Strogoff: The Courier of the Czar (French: Michel Strogoff) is a novel written by Jules Verne in 1876. Critic Leonard S. Davidow, considers it one of Verne's best books. Davidow wrote, "Jules Verne has written no better book than this, in fact it is deservedly ranked as one of the most thrilling tales ever written." Unlike some of Verne's other novels, it is not science fiction, but its plot device is a scientific phenomenon (Leidenfrost effect). The book was later adapted to a play, by Verne himself and Adolphe d'Ennery. Incidental music to the play was written by Alexandre Artus in 1880 and by Franz von Suppé in 1893. The book has been adapted several times for films, television and cartoon series.

Captain Nemo (/ˈneɪmoʊ/; also known as Prince Dakkar) 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).

Nemo is a mysterious figure. Though of unknown nationality in the first book, he is described as the son of an Indian raja in the second book. A scientific visionary, he roams the depths of the seas in his submarine, the Nautilus, which was assembled from parts manufactured in several different countries, then shipped to a cover address. The captain is consumed by a hunger for vengeance and hatred of imperialism; Verne included references to anti-imperialist uprisings, including the Kościuszko Uprising and Indian Rebellion of 1857, in the various backstories of Nemo.
