Before the term "transgender" existed, there were those who experienced their gender in complex ways. examines the lives and writings of Jane Dieulafoy (1850–1916), Rachilde (1860–1953), and Marc de Montifaud (1845–1912), three French writers whose gender expression did not conform to nineteenth-century notions of femininity. Dieulafoy fought alongside her husband in the Franco-Prussian War and traveled with him to the Middle East; later she wrote novels about girls becoming boys and enjoyed being photographed in her signature men's suits. Rachilde became famous in the 1880s for her controversial gender-bending novel , published around the same time that she started using a calling card that read "Rachilde, Man of Letters." Montifaud began her career as an art critic before turning to erotic writings, for which she was repeatedly charged with "offense to public decency"; she wore tailored men's suits and a short haircut for much of her life and went by masculine pronouns among certain friends. Dieulafoy, Rachilde, and Montifaud established themselves as fixtures in the literary world of fin-de-siècle Paris at the same time as French writers, scientists, and doctors were becoming increasingly fascinated with sexuality and sexual difference. Even so, the concept of gender identity as separate from sexual identity did not yet exist. explores these three figures' lifelong efforts to articulate a sense of selfhood that did not precisely align with the conventional gender roles of their day. Their intricate, personal stories provide vital historical context for our own efforts to understand the nature of gender identity and the ways in which it might be expressed.
