Many notable French writers have not become members of the Académie Française. During 1855, the writer Arsène Houssaye devised the expression "forty-first seat" for deserving individuals who were never elected to the Académie, either because their candidacies were rejected, because they were never candidates, or because they died before appropriate vacancies arose. Notable French authors who never became academicians include Jean-Jacques Rousseau, Jean-Paul Sartre, Joseph de Maistre, Honoré de Balzac, René Descartes, Denis Diderot, Romain Rolland, Charles Baudelaire, Gustave Flaubert, Molière, Marcel Proust, Jules Verne, Théophile Gautier, and Émile Zola.
