Pictured above is Gaspard-Félix Tournachon, better known by the pseudonym Nadar, who was a French photographer in the nineteenth century, just when aeronautics and air travel were entering popular culture. He was fascinated by human flight, and in 1858 he became the first person to successfully take aerial photographs while he was in a balloon. He subsequently commissioned balloons to be designed and built, and he would allow passengers to take flights with him. He was no doubt obsessed with verticality, and his aerial photographs mark a major turning point in the history of human flight.
