Halévy became a disciple and collaborator of Saint-Simon, aiding in the foundation of his journal, Le Producteur, and writing the introduction to his work, Opinions Littéraires, Philosophiques et Industrielles, in which Olinde Rodrigues and Étienne-Martin Bailly also assisted.
In 1837, Halévy was attached to the Ministry of Public Instruction as chief of the bureau of scientific societies, and remained there until his retirement in 1853, after which he devoted the remainder of his life to literature, writing a large number of poems, translations, plays, and other works.
