Gaspard-Félix Tournachon was born April 6, 1820, in Paris, France. Under the name Nadar, he sold caricatures to humor magazines, then opened a photographic portrait studio. Nadar's portraits were a hit, and he began to innovate, building a giant balloon named Le Géant ("The Giant"), powered by gas, to take the world's first aerial photograph. He also shot the Paris sewer system under electric light, and experimented with serial photography. Nadar died in Paris on March 20, 1910.
