New York: Harcourt Brace, 1931. First Edition. Large octavo. Black cloth boards (hardcover); 346pp; 12 inserted leaves of plates (halftones). Brief pencil annotation inside front cover, else a tight, VG or better copy, free of textual markings or significant wear. Though clearly superseded by later scholarship, Josephson's remains one of the most readable biographies of Rousseau, praised by Peter Gay as "...racy, well-informed, and sympathetic" and among the few "satisfactory" Rousseau biographies.
