Jean Marni or J. Marni ( Jeanne-Marie-Francoise Barousse; Mme. Marniere; 1851–1910) was a French writer. She wrote novels, plays, and journalistic pieces.[1] She published a short story at the age of eight, but her other works were published after 1885, after she became a widow.[2] Known by her pseudonym, J. Marni, she wrote a number of novels that were very French in tone. The best known are La Femme de Silva, L'Amour Coupable, Papote, and La Princesse Sablina. Others of her works, that have been translated into English and other languages, include Frangoise, Reaction, Le Veilleur and La Piece do Vin. She took up subjects considered repugnant to a woman of her time, and wrote them "threadbare". Most of her works are psychological studies—analyses of the human passions. She had a large following of readers in France.[3]
