As a measure of his popularity, 40 volumes of his collected works were published in Imperial Russia in 1911.
A physician by profession, Boussenard travelled throughout the French colonies, especially in Africa.
He was drafted during the Franco-Prussian War but soon capitulated to the Prussian soldiers, a bitter experience that could explain a nationalist flavour present in many of his novels.
L'île en feu (1898) fictionalized Cuba's struggle for independence.
Aspiring to emulate Jules Verne, Boussenard also turned out several science fiction novels, notably Les secrets de monsieur Synthèse (1888) and Dix mille ans dans un bloc de glace (1890), both translated by Brian Stableford in 2013 under the title Monsieur Synthesis ISBN 978-1-61227-161-3
