H. de (Henry) Graffigny

Born Raoul Henri Clément Auguste Antoine Marquis in 1863, this French author wrote under the name Henry de Graffigny, taken from his birthplace, Graffigny-Chemin. He built a remarkably varied career as a writer, journalist, and popularizer of science, producing fiction as well as practical and scientific works for general readers.

He is especially remembered for adventure and speculative fiction linked to the scientific imagination of his era. With Georges Le Faure, he wrote the Aventures extraordinaires d'un savant russe series, and his work often drew on subjects such as aviation, engineering, and new technology.

De Graffigny was also active in the world of aeronautics and science journalism, and reliable sources describe him as an editor of a science magazine as well as an amateur scientist. He died in 1934, leaving behind a body of work that captures the excitement people felt as modern science seemed to open entirely new worlds.
