Julienne Alexandrine Mathieu (September 21, 1874 - December 1, 1943) was one of the earliest French silent film actresses who appeared mostly in French silents between 1905 and 1909. She appeared in the silent film Hôtel électrique released in 1908, one of the first films to incorporate stop animation. She was the wife of the director Segundo de Chomón. Her contribution to his work was not only her participation in the cast, but also in the script and the special effects (in particular, Pathécolor process to which she introduced her husband).
