Gustave Caillebotte

Gustave Caillebotte was a French painter and a member of the Impressionist group, though his style was more realistic than that of many of his peers. He took an early interest in photography as an art form. His family's wealth allowed him to support fellow Impressionists, and the collection of their works he bequeathed became central to the French Republic's holdings of Impressionism.
