Barbizon school
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.
