Mathilde Henriette Delattre (1871 – 1950) was a French painter known for her work during the late 19th and early 20th centuries. Thanks to her mother, she received a strong foundation in painting techniques from private masters, as Beaux-Arts national school was still forbidden to women at the time. Delattre career was associated with the Union des Femmes Peintres et Sculpteurs, a pioneering organization dedicated to promoting the work and rights of women artists in a male-dominated field. She exhibited her works at various exhibitions, including the prestigious Salon des artistes français in Paris. Delattre’s oeuvre includes a variety of subjects such as portraits and landscapes, but focuses on still lifes and floral watercolors. Her work associates realism with a sensitive atmosphere. Delattre gained recognition within the artistic community, and as a teacher, her Parisian workshop was very busy. While not as widely known today as some of her contemporaries, Mathilde Delattre’s work and involvement in the art community highlight the significant yet often under-recognized contributions of women artists during a transformative period in art history.
