Olivia Rossetti Agresti (1875–1960) was a British activist, author, editor, and interpreter. A member of one of England's most prominent artistic and literary families, her unconventional political trajectory began with anarchism, continued with the League of Nations, and ended with Italian Fascism. Her involvement with the latter led to an important correspondence and friendship with Ezra Pound, who mentions her twice in his Cantos.
While still in their girlhood, Olivia and her sister, the future Helen Rossetti Angeli (1879–1969), began publishing an anarchist journal, The Torch. Years later, using the pseudonym "Isabel Meredith", Olivia and Helen published A Girl Among the Anarchists, a somewhat fictionalized memoir of their days as precocious child revolutionaries.[1]
