During the 19th century, Paris was the home and subject for some of France's greatest writers, including Charles Baudelaire, Stéphane Mallarmé, Mérimée, Alfred de Musset, Marcel Proust, Émile Zola, Alexandre Dumas, Gustave Flaubert, Guy de Maupassant and Honoré de Balzac. Victor Hugo's The Hunchback of Notre Dame inspired the renovation of its setting, the Notre-Dame de Paris. Another of Victor Hugo's works, Les Misérables, written while he was in exile outside France during the Second Empire, described the social change and political turmoil in Paris in the early 1830s. One of the most popular of all French writers, Jules Verne, worked at the Theatre Lyrique and the Paris stock exchange, while he did research for his stories at the National Library.
