Georges Sorel
A rebellious aristocrat and landowner, Diamandy was introduced to socialism ca. 1887, when he wrote his first articles in the Marxist review "Contemporanul". In the 1890s, he had set up in Paris his own "L'Ère Nouvelle", which represented a heterodox form of Marxism, and helped launch the writing career of Georges Sorel. As the latter noted, Diamandy was an "unreliable" character, who "simply disappeared" from his life at some point.
