Eugène Viollet-le-Duc, French architect, designed the Lausanne Cathedral (d. 1879)
Eugène Emmanuel Viollet-le-Duc (French: [øʒɛn vjɔlɛlədyk]; 27 January 1814 – 17 September 1879) was a French architect and author who restored many prominent medieval landmarks in France, including those which had been damaged or abandoned during the French Revolution. His major restoration projects included Notre-Dame de Paris, the Basilica of Saint Denis, Mont Saint-Michel, Sainte-Chapelle, and the medieval walls of the city of Carcassonne, and he planned much of the physical construction of the Statue of Liberty (Liberty Enlightening the World). His later writings on the relationship between form and function in architecture had a notable influence on a new generation of architects, including Victor Horta, Hector Guimard, Antoni Gaudí, Hendrik Petrus Berlage, Louis Sullivan and Frank Lloyd Wright.
