Jacqueline Marval was the pseudonym for Marie Josephine Vallet (1866–1932), a French painter, lithographer, and sculptor.
Vallet was born 19 October 1866, in Quaix-en-Chartreuse into a family of schoolteachers.
She separated from her husband in 1891 and earned a living making waistcoats.
In 1894, she met the painter François Joseph Girot and began living with him in Paris as his lover.
The next year, she met Jules Flandrin, another painter and a student of Gustave Moreau.
The two fell in love, and Vallet left Girot to move in with Flandrin in Rue Campagne-Première, in the Montparnasse area.
She created a series of twelve paintings on the theme of Daphnis and Chloe, completing them in 1913.
The same year, she protested against the removal from the Salon d'Automne of Kees van Dongen's The Spanish Shawl, and became friends with van Dongen, setting up her studio near his.
In 1913, Francis Picabia displayed Marval's 1903 painting The Odalisques in the Armory Show, an important exhibition of modern art in New York.
This painting depicted five women: three seated nude, one dressed and reclining on her elbow, and one standing and holding a tray.
Guillaume Apollinaire wrote of this painting in the Chronique des arts that "Mme.
She was given the epithet "the fairy of the Belle Époque."
Beginning in 1923, Marval was active in favor of the creation of modern art museums in Paris and Grenoble.
She died in Paris in 1932; after her death, her works were held in the galerie Druet before it was closed in 1938 and they were sold.
Her painting Portrait of Dolly Davis, 1925 is in the collection of the Milwaukee Art Museum.
Stylistically, "Marval's paintings are provocative and edgy, challenging and unusual, she was an important modernist at the earliest moments of the movement."
