„We also consider that Miss Berthe Morisot's [woman painter in French Impressionism who got later married with a brother of Eduard Manet] name and talent are too important to us to do without. [Degas is referring to her participation in the first Impressionist's show he was preparing, then; he was in strong opposition to Eduard Manet who wanted to exclude Berthe Morisot)“
