Emil Offenbacher attempts to prove in this short paper that Strindberg, when he wrote his drama, Miss Julia, had known the Mademoiselle Tantale of J. L. Dubut de Laforest. Offenbacher finds striking similarity in the general theme and in details of both life stories. The multiple motives for the pathological behavior of the heroines are the same. The paper has more interest as literary history than as psychology.
