In 1865 Paul took over the family business which represented artists such as Corot and the Barbizon school of French landscape painting. In 1867 he moved his gallery from 1 rue de la Paix, Paris, to 16 rue Laffitte, with a branch at 111 rue Le Peletier. During the 1860s and early 1870s Durand-Ruel was an important advocate and successful art dealer of the Barbizon School but he is best known for his relationship with a group of painters who would become known as the Impressionists.
