The strong portrait of Adam Jerzy Czartoryski (1770 - 1861) was made by Félix Tournachon, better known as Nadar. The Polish statesman was photographed in the outdoor studio at Nadar's first studio address, rue Saint-Lazare, 113.
The print is mounted on a cardboard with the stamp of photographer Alexandre Valtier. He had a studio in the same street as Nadar: Boulevard des Capucines 11, Valtier's second address. However, it is certain that the shot was taken by Félix Nadar. We add a later gelatine silver print, made after the original negatives, from the same sitting. There are several examples of this portrait to be found in the BnF archives in Paris.
On the left of the portrait, original retouching is visible. Was Nadar's signature and address removed in this way? In any case, we found the same portrait in a Polish collection where the signature is clearly visible in exactly this place in the portrait.

Czartoryski, was a Polish nobleman, statesman, diplomat and author who served as Chairman of the Council of Ministers of the Russian Empire.
He began his political career as a foreign minister to Emperor Alexander I of Russia after Poland was partitioned by Russia, Prussia and Austria. He later became a leader of the Polish government in exile during and after the failed November Uprising (1830–1831) and a bitter opponent of Alexander's successor, Nicholas I. In exile, he advocated for the reestablishment of a sovereign Polish state, which also stimulated early Balkan and Belgian nationalism, and intensified their desire for independence. From 1832 he lived in Paris.

A slightly different version of this portrait was printed by Charles Nègre as a Heliogravure. See last image for reference only.
