(Poujol 2003, p. 243) Eugenie wrote about her own family background in the last part of her literary work, The Real Book of Women (Le vrai livre des femmes[1]): "I come from a literate family with origins from Geneva, Switzerland," she wrote before emphasizing the importance of her grandfather Pierre Mouchon, an erudite pastor in Geneva and contributor to the Encyclopédie of Diderot and d’Alembert.

[2] Only afterward did she mention her father, who came to France to study at the Faculty of Medicine of Montpellier, and her mother by simply stating, "He married the daughter of a pastor from Gar," which indicated a Protestant origin.

In her autobiography, Eugénie emphasized the commitment of her family to Napoleon as one reason for the choice of her husband: "As a Child of the Empire, I could not marry anyone but an imperialist."

On July 20, 1830, Barthelemy Prosper Enfantin, one of the founders of Saint-Simonianism, appointed four women members of the college: Aglae Saint-Hilaire, Caroline Simon, Madame Collard and Eugenie Niboyet.

Like the two founders and participants in the first issues of The Free Woman, she drew closer to the movement of the philosopher Charles Fourier, who presented the treatment of women as the truest measure of social progress.

Back in Lyon in 1833, Eugenie founded the first feminist periodical outside the Paris region with a publication titled The Women's Advisor (Le Conseiller des femmes), a weekly without illustrations printed by Boitel, followed for a few months by The Lyonese Mosaic (La Mosaïque Lyonnaise).

[6] A sort of club, bringing together editors and subscribers, met to support and manage the newspaper, but also to discuss particular issues including the struggle for political and civil rights of women.

[7] The revolution of 1848 gave new hope to feminism, including the lifting of restrictions on meetings, thereby allowing the development of groups that advocated for women's rights.

Eugénie managed to assemble many women already involved in the feminist struggle such as Jeanne Deroin, Desiree Gay, Suzanne Voilquin, Elisa Lemonnier, and Anais Segalas,[8] but also popular authors such as Gabrielle Soumet, Amelie Prai, and Adèle Esquiros.

Extending the right to vote to all men provoked a resounding initiative when, on April 6, The Voice of Women nominated the candidacy of George Sand to the French Constituent Assembly.

On June 20, Eugénie Niboyet, discouraged and hurt, ceased publication of The Voice of Women, and the feminists dispersed to avoid repression.

[9] Her letters to Leon Richer, the editor of The Rights of Women (Le Droit des femmes), attest to the fact that she always remained interested in the feminist movement.
