en Cuevana 3. April 15, 1874, boulevard des Capucines, Paris: a group of young feverish painters shunned by the official Salon and mocked by the classical masters, chose to come together to exhibit their paintings freely, in the studio of photographer Nadar. At the end of a teeming century, when modernity was emerging, this group of rebellious artists, revolutionized the world of art.
