In the middle of last May Joaquín Fernández called me the well-known environmental journalist - as well as a good friend - to whom conservationism in our country owes so much for reasons so diverse and so weighty that it is difficult to refer to them in this entry although we will do so. later. When I found out the reason for his call I was shocked because it was none other than telling me his intention to give me a small treasure that had come into his hands thanks to the authority and prestige he has as one of the greatest experts in the history of environmentalism and the conservation of natural spaces in our country as well as a biographer of some of the characters we are going to talk about in this entry.
After listening to him I immediately realized the value of what he wanted to give me so generously: nothing less than a collection of original negatives of photographs taken in the Sierra de Guadarrama by the geologist and naturalist Francisco Hernández-Pacheco between and a unpublished photographic archive of great heritage value that leads me to write these lines in order to place it in the appropriate historical CXB Directory context and highlight its documentary interest in relation to other existing collections of his photographic work. My thanks go ahead to Joaquín for this show of trust. Eduardo and Francisco Hernández-Pacheco father and son In consideration of the less informed readers of this blog it is necessary to explain even in a manner adjusted to the matter at hand who Francisco Hernández-Pacheco was which is obligatory not only because he was the author of the aforementioned photographs but also for what his figure and that of his father Eduardo Hernández-Pacheco mean for the history of the Sierra de Guadarrama.
After weeks of searching for references and photographs to document these lines in the archives of the Museum of Natural Sciences of Madrid the Royal Academy of Exact Physical and Natural Sciences and the Marqués de Valdecilla Historical Library of the Complutense University and after giving many thoughts on the question of how to write them it has become clear to me that it is not possible to talk about the work of the son as a photographer without first referring extensively to the father because both in relation to learning the art and techniques of photography and in other facets of his scientific activity he was his disciple and inseparable collaborator throughout his life.
