LOUIS DUCOS DU HAURON

'Louis Ducos du Hauron' (December 8, 1837 – August 31, 1920) was a French pioneer of color photography. He was born in Langon, Gironde and he died in Agen.
In the years following his unpublished paper of 1862 he set out practical ways of recording colour images using both additive (red, green, blue) and subtractive (cyan, magenta, yellow) methods. In 1868 he patented some of his methods and in 1869 he wrote ''Les Couleurs en Photographie.'' One of his earliest color photographs is the ''Landscape of Southern France'', taken by the subtractive method in 1877.
