Nadar, pseudonym of 
Gaspard-Félix Tournachon   (born  April 5, 1820, Paris, France—died  March 21, 1910, Paris), French  writer, caricaturist, and photographer who is remembered primarily for  his 
photographic portraits, which are considered to be among the best done in the 19th century. 
As a young man, he studied medicine in Lyon, France, but, when his  father’s publishing house went bankrupt in 1838, he was forced to earn  his own livelihood. He began to write newspaper articles that he signed  “Nadar.” In 1842 he settled in Paris and began to sell caricatures to  humour magazines.
By 1853, although he still considered himself primarily a  caricaturist, Nadar had become an expert photographer and had opened a  portrait studio. His immediate success stemmed partly from his sense of  showmanship. He had the entire building that housed his studio painted  red and his name printed in gigantic letters across a 50-foot (15-metre)  expanse of wall. The building became a local landmark and a favourite  meeting place of the intelligentsia of Paris. When in 1874 the painters  later known as Impressionists needed a place to hold their first  exhibit, Nadar lent them his 
gallery. He was greatly pleased by the storm the exhibit raised; the notoriety was good for business.
In 1854 he completed his first 
Panthéon-Nadar, a set of two gigantic lithographs portraying caricatures of prominent Parisians. When he began work on the second 
Panthéon-Nadar, he made photographic portraits of the persons he intended to caricature. His 
portraits of the illustrator 
Gustave Doré (
c. 1855) and the poet 
Charles Baudelaire (1855) are direct and naturally posed, in contrast to the stiff formality of most contemporaneous portraits. Other remarkable character studies are those of the writer 
Théophile Gautier (
c. 1855) and the painter 
Eugène Delacroix (1855).
Nadar was a tireless innovator. In 1855 he patented the idea of using 
aerial photographs  in mapmaking and surveying. It was not until 1858, however, that he was  able to make a successful aerial photograph—the world’s first—from a  balloon. This led Daumier to issue a satirical lithograph of Nadar  photographing Paris from a balloon. It was titled 
Nadar Raising Photography to the Height of Art. Nadar remained a passionate aeronaut until he and his wife and other passengers were injured in an accident in 
Le Géant, a gigantic balloon he had built.
In 1858 he began to photograph by electric light, making a series of  photographs of Paris sewers. Later, in 1886, he made the first

Michel-Eugène Chevreul  in conversation. Each picture was captioned with Chevreul’s responses  to Nadar’s questions, giving a vivid impression of the scientist’s  personality. Nadar also wrote novels, essays, satires, and  autobio
