Throughout her life Julie posed frequently for her mother and other Impressionist artists, including Renoir and her uncle Édouard.

Her teenage diary, published in English as Growing up with the Impressionists, provides insights into the lives of French painters, including Renoir, Degas, Monet, and Sisley, as well the 1896 state visit of Tsar Nicholas II and the Dreyfus Affair, which was then raging in France.

Notably, her candid accounts of dinner-table conversations about the Dreyfus Affair cast light on Renoir's privately held views on patriotism and anti-Semitism.

Both Julien and Denis inherited some of Morisot's paintings, now in the Marmottan Monet Museum.
