Era un comerciante de ropa que en la década de 1840 se empezó a interesar por la fotografía. Estudió el calotipo y en 1847 fue el primero en difundir este procedimiento en Francia, mejoró sustancialmente el proceso al emplear nitrato de plata, yoduro de potasio y situando el papel húmedo directamente en la cámara entre dos cristales. En 1850 desarrolló y publicó la técnica de la copia en papel a la albúmina, que alcanzó pronto un gran éxito.



Louis Désiré Blanquart-Evrard was a cloth merchant from Lille, France who learned the calotype process from his druggist, a student of the inventor of the calotype, William Henry Fox Talbot. In 1847 Blanquart-Evrard became the first to publish the procedure for the calotype negative/positive paper process in France. He specialized in printing and issuing portfolios of photographs by other photographers, but perhaps his most significant contribution was the introduction in 1850 of the albumen paper print process, the primary printing medium until gelatin papers superceded it in the late 1800s.
