Didier Cornille was a student of Claude Courtecuisse at the Lille Fine Arts School. He then joined Roger Tallon's design department at the Arts Décoratifs in Paris. During his studies he met the designer Ettore Sottsass in Milan, who steered his work as a designer. He then turned to the creation of lamps, often in animal shapes, that he exhibits at the Neotu gallery.

After teaching design at the fine arts in Tunis, then in Tourcoing and at LISAA (Institut Supérieur des Arts Appliqués) in Paris, he taught design for a long time at Le Mans Fine arts School. Today, he devotes his time to his books and his work as a designer. He lives in Paris.
