From Wikipedia, the free encyclopedia
Louis Désiré Blanquart-Evrard (1802 - 1872) was a French cloth merchant by trade but, in the 1840's, was also a student of the new art form of photography. He studied the Calotype process, and in 1847, became the first of his countrymen to publish the process in France. In 1850 he developed and introduced the albumen paper printing technique which became the staple process of the soon to be popular Carte de visite print.[1]
