In 1895 Córdoba’s State Government commissioned the authors, who were well trained engineers and true scientists, for the challenging task of writing a Geography of the Province. After eight years, that included five of arduous field work, it was published in 1904. It became a true milestone in the field, since it was the first ever written in Argentina, and probably in South America, that applied contemporary concepts, techniques and methodology. It was received with unanimous praise both locally and abroad. The analysis and comments of prestigious international publications were unanimously laudatory, which is surprising to anyone familiar with the formal and reserved style of first line European and Anglo-Saxon editors and commentators. All of this, and much more, can be found in the Commemorative Volume, edited on the Geography’s 100th anniversary that is included in the present publication as a separate file.
