Gaspard-Félix Tournachon (6 April 1820 – 20 March 1910), known by the pseudonym Nadar, was a French photographer. Nadar is especially famous for his gallery of portraits of the celebrities of his time, writers, artists and politicians. His studio collection is today kept at the Media Library of Architecture and Heritage, but many pictures are also in the collections of the world’s greatest museums, including the Musée d’Orsay. In 1858 he became the first person to take aerial photographs. In 1860, Nadar opened a large store on Boulevard des Capucines, on this axis frequented by all Parisian people. It is one of the floors that he rents out to Impressionist painters for their first exhibition in 1874. A last burst of fame reaches him during the Universal Exhibition of 1900, where his work is hailed. His end of life is less glorious, and he settles in the South of France, where he died in 1858, after building a huge balloon capable of carrying several dozen people on board.
