Jules Verne

Jules Gabriel Verne (8 February 1828 – 24 March 1905) was a French novelist, poet, and playwright. Verne's collaboration with the publisher Pierre-Jules Hetzel led to the creation of the Voyages extraordinaires, a widely popular series of scrupulously researched adventure novels including Journey to the Center of the Earth (1864), Twenty Thousand Leagues Under the Sea (1870), and Around the World in Eighty Days (1873). Verne is generally considered a major literary author in France and most of Europe, where he has had a wide influence on the literary avant-garde and on surrealism. (Wikipedia)
