The letter from Jeanne Deroin to Proudhon that I just posted appeared in French in L’Opinion de Femmes, a radical feminist journal edited by Deroin and Désirée Gay. The entire run of the paper can be found at Gallica, tucked away in one of the volumes of Les Révolutions du XIXe Siècle. L’Opinion des Femmes is great stuff, with material by Deroin, Gay, Jean Macé, C. F. Chevé, and “Jeanne Marie” (probably Jeanne-Marie-Fabienne Poinsard, aka Jenny d’Héricourt.) The beginnings of the feud between Deroin and Proudhon is documented.
Expect to see a lot of translations from this paper over the next year or so.
