Eugene -Emnanuel Viollet-le-Duc

French architect and writer. The self -taught architect Viollet -le -Duc was the most famous proponent of the Gothic Revival in France. He was best known for restorations at Pierrefonds and Notre Dame cathedral in Paris, but despite his reverence for the Gothic, he was also a critic of eclectic historicism. His lectures Entretiens sur L’architecture (Treatises on Architecture; 1863 -72) advocated the adventurous use of iron and glass. Art Nouveau architects including Victor Horta, Hector Guimard, Antoni Gaudi and Louis Sullivan all cited Viollet as an influence.
