Dénoix produced her first poetry collection in 1837, "Hours of Solitude", and perhaps her most ambitious endeavor was to translate into verse the "Mysteries of Paris" by Eugène Sue (1843). After the 1848 French revolution, Fanny Dénoix became actively involved in politics, publishing an ode to the army (1850), a collection of patriotic verses (1855), and a salute to Pierre-Joseph Proudhon (1858).
