French photographer, caricaturist, journalist, novelist, and balloonist.
He took his first photographs in 1853 and in 1858 became the first person to take aerial photographs. He also pioneered the use of artificial lighting in photography, working in the catacombs of Paris.
Around 1863, Nadar built a huge (6000 m³) balloon named Le Géant (“The Giant”), thereby inspiring Jules Verne’s Five Weeks in a Balloon. Although the “Géant” project was initially unsuccessful Nadar was still convinced that the future belonged to heavier-than-air machines. Later, “The Society for the Encouragement of Aerial Locomotion by Means of Heavier than Air Machines” was established, with Nadar as president and Verne as secretary. Nadar was also the inspiration for the character of Michael Ardan in Verne’s From the Earth to the Moon.
On his visit to Brussels with the Géant, on 26 September 1864, Nadar erected mobile barriers to keep the crowd at a safe distance. Up to this day, crowd control barriers are known in Belgium as Nadar barriers.
In April 1874, he lent his photo studio to a group of painters, thus making the first exhibition of the Impressionists possible. He photographed Victor Hugo on his death-bed in 1885. He is credited with having published (in 1886) the first photo-interview (of famous chemist Michel Eugène Chevreul, then a centenarian), and also took took erotic photographs.
He died 23 March 1910.
