The photographic universe built by the European explorer, which consists of several hundred photographs, constitutes a valuable, original and unrepeatable historical and ethnographic memory that must be part of the Colombian photographic and cultural heritage. It is a pioneering photographic work since, within the history of photography in Colombia placed at the service of anthropology, only the work of the German ethnographer Theodor Koch-Grünberg between the years of 1903-1905, who left us a valuable Photographic record of some indigenous groups of Miritiparaná - Apaporis. Decades later, during World War II, the illustrious Botanist Richard Evans Schultes began his investigations and achieved other of the most recognized photographic records, particularly on the Colombian Amazon rainforest. Since the mid-twentieth century, the very famous researcher Gerardo Reichel Dolmatoff started another of the most monumental photographic works that today is preserved thanks to the Luis Ángel Arango Library.
