Cause of death: hemorrhage
Jules-Amédée Barbey d'Aurevilly (2 November 1808 – 23 April 1889) was a French novelist, poet, short story writer, and literary critic. He specialised in mystery tales that explored hidden motivation and hinted at evil without being explicitly concerned with anything supernatural. He had a decisive influence on writers such as Auguste Villiers de l'Isle-Adam, Henry James, Léon Bloy, and Marcel Proust.
