A traveler, archaeologist, and photographer, Désiré Charnay (1828-1915) was one of the most important early expeditionary photographers. During his tours of Yucatan, Oaxaca, and Chiapas in 1858-1860 and 1880-1886, Charnay became one of the first to use photography in documenting the great Meso-American archaeological sites and to make ethnographic photographs of indigenous Mexicans. His major publications Cités et Ruines Américaines (Paris, 1862) and Les Anciennes Villes du Nouveau Monde (Paris, 1885) are important transitional works to the later scientific archaeology of Alfred Maudslay. The collection of photographs taken by Desire Charnay are representative of the range of images he took of Meso-American archaeological sites during three tours of Mexico in 1858-1860 and 1880-1886. Although some of the images have suffered an unfortunate degree of fading, they convey the power and fascination that these sites held for Charnay and his contemporaries, and include some of the best early examples of the use of photography in the documentation of Mexican archaeology. The collection includes 123 images of the sites at Tula, Teotihuacan, Iztaccihuatl, Chichen Itza, Comalcalco, and Palenque, of archaeological specimens held at the Museum of Mexico, and of landscape and villages in Yucatan, Chiapas, and Oaxaca, as well as a series of Lacandon, Mayan, Mixtec, and Yucatec "racial types."
