Yet her output was prodigious. Of the nearly four hundred films Guy directed between 1896 and 1920, Guy has two main periods of work as a director: for Leon Gaumont’s studios, where she began her career after breaking out of the secretarial pool in 1896 to become, within a short space of time, the principal director for the studio; and in the United States for her own company, Solax, which flourished for a few brief years after the turn of the century in Fort Lee, New Jersey. Yet much of her work is lost. For a long time, only a handful of Guy’s many films were thought to have survived, among them Les Cambrioleurs (1898), Surprise d’une maison au petit jour (Episode de la Guerre de 1870) (1898), Les Maçons (1905), Le Fils du garde-chasse (1906), Le Noël de monsieur le Curé (1906), and La Course à la saucisse (1907).
