1859–1948
A pioneer of early science fiction, this Belgian-born writer helped imagine strange worlds, future possibilities, and deep prehistory long before those themes became mainstream. His stories mix adventure with curiosity about humanity, nature, and evolution.

by aîné J.-H. Rosny, jeune J.-H. Rosny
Born in Brussels in 1859 as Séraphin Justin François Boex, he became known as J.-H. Rosny jeune. Early in his career he wrote together with his older brother under the shared name J.-H. Rosny; after they separated their literary identities in the early 20th century, he continued publishing as Rosny jeune.
He is often remembered as one of the early builders of modern science fiction in French. His work ranges across speculative fiction, fantasy, and prehistoric tales, with a strong interest in science, natural forces, and the long story of human life.
Rosny jeune died in 1948. Readers who come to him today often find a writer from the dawn of science fiction who was already thinking on a grand scale about other beings, ancient worlds, and the place of humanity in the universe.
