Arnould Galopin (1865-1934) was a prolific French author during the first three decades of the 20th century with over fifty novels to his credit. Galopin won the French Academy's Grand Prize for his Sur le Front de Mer [On the Sea Front], and wrote several critically acclaimed novels about his experience during World War I. Galopin wrote a number of science fiction novels in the Jules Verne tradition, including Doctor Oméga, La Révolution de Demain [Tomorrow's Revolution] (1909), and Le Bacille (1928), a prophetic tale of a mad scientist who uses bacteriological warfare for revenge.  Finally, Galopin was the creator of the fictional detective Allan (Harry) Dickson, who teamed up with Sherlock Holmes in L'Homme au Complet Gris [The Man In Grey] (1910), one of the earliest French Holmesian pastiches.
