Marie Joséphine Charlotte du Val d'Ognes (1786–1868)

In 1917, The Met purchased this portrait of a young woman artist for $200,000. At the time, it was thought to be painted by the male Neoclassical artist, Jacques-Louis David. Art historian Kathryn Calley Galitz shares how the scholar Margaret Oppenheimer made a surprising discovery when she reevaluated that attribution more than half a century later.
