Nadar, the pseudonym of Gaspard-Félix Tournachon (1820–1910), was a French photographer, caricaturist, writer and balloonist, and the great portraitist of nineteenth-century Paris. In his studio he photographed the writers, painters, musicians and actors of his time — Baudelaire, Dumas, Rossini, Doré, Manet — against plain backgrounds and in natural light, seeking what he called the moral likeness of his sitters. He was the first to take aerial photographs from a balloon and to photograph the catacombs of Paris by electric light, and in 1874 he lent his studio to the first Impressionist exhibition.
