When searching the net for Baudelaire, Hugo, Mallarmé, it is not unusual to find "[...] photographed by Nadar" written under their pictures. But who was Nadar? The question just popped into my head while noticing how many great personalities this name has photographed.

Nadar was the pseudonym used by a man named Gaspard-Félix Tournachon, born on April, the 6th 1820 in the city of Paris, where he died in 1910 and rests now in the Père Lachaise cemetery. Not only he photographed almost tens of poets, writers, painters during his life, he was also the first photographer to take aerial photos and use artificial lighting. 
In France, the prix Nadar is a photojournalism prize given in the photographer's name.  
Plus, he is definitely someone those who love Impressionism should be grateful to. 30 impressionist painters first exposed their works in an exhibition which took place in Nadar photo studio. Among these, there were Monet, Pissarro, Renoir, Degas and Cézanne. Manet refused to participate.

Just a short list of personalities photographed by Nadar:

Charles Baudelaire

Victor Hugo

Gioacchino Rossini 

Sarah Bernhardt

Gustave Courbet

Eugène Delacroix

Alexandre Dumas (father)

Jules Verne

Franz Liszt

Stéphane Mallarmé
