Louis Désiré Blanquart-Evrard (2 August 1802 – 28 April 1872) was a French inventor, photographer and publisher of photographs. He was a cloth merchant by trade, developing an interest in photography in the 1840s, focusing on the technical and economic issues of the mass production of photographic prints. Blanquart-Evrard captured this seated self-portrait in 1869, processed as an albumen print, a technique that he had developed himself in 1847. This photograph is in the collection of the Bibliothèque nationale de France.Photograph credit: Louis Désiré Blanquart-Evrard; restored by Jebulon
