Born in New York in 1935, Robert Silverberg published his first novel, Revolt on Alpha C, at only 19 years old. The Hugo prize for the most promising author he obtained in 1955 announced a great career. It was not until 1968 that the author refined his style and found a real outlet in the field of science fiction with L'Homme in the labyrinthe et The wings of the night. In the 1970s, he enjoyed success with L'oreille interne, Le livres des Crânes and in 1980 Le château de Lord Valentin.

Multi-awarded and considered a staple of SF literature, Robert Silverberg now lives in San Francisco. He entrusted Humanoïdes Associés and authors Philippe Thirault and Laura Zuccheri, the honor of adapting his novel The Profondeurs de la Terre into a comic strip.
