ABSTRACT This article examines the evolution of nineteenth-century French economist Michel Chevalier’s reputation and self-understanding as a Saint-Simonian. Despite only having served two years as chief editor of the famous Saint-Simonian Globe, Chevalier’s attempt to re-integrate himself into liberal intellectual circles following his split from the Saint-Simonian movement was consistently hindered by his perceived adherence to its illiberal principles. This article mobilizes Chevalier’s reputation as a means to explore the porous boundary between Saint-Simonianism and French liberalism at a time when the contours between the two traditions were still not clearly defined. I also argue that the economist’s continued prioritization of economic development over political liberty grounded a variety of liberalism that many political liberals found intolerable, notably in its willingness to endure Bonapartist authoritarianism for the sake of economic growth. Mobilizing new archival material from the Second Empire, this article illuminates how Chevalier and others understood his relation to Saint-Simonianism and liberalism in the moment when he was at the apogee of his power and influence.
