Jean Grave (1854-1939) was a leading French anarchist whose theoretical works and activity place him alongside such luminaries as William Godwin, Pierre-Joseph Proudhon, Michael Bakunin and Peter Kropotkin. Now, drawing on various archival and library sorces, Louis Patsouras traces the controversies and convictions that shaped the life and career of this extraordinary radical thinker, and in doing so pays tribute to an anarchist tradition that continued in Weil, Camus and Sartre.
