Alexander Rodchenko was one of the main generators of creative ideas during the extraordinary time of the Russian avant-garde movements, and he perfectly reflected its spiritual atmosphere. In 1924, photography was "invaded" by Alexander Rodchenko. The result of this invasion was a fundamental rethinking on the nature of photography and the role of the photographer. With the introduction of conceptual thought, the photograph changed from being a mere reflection of reality to a means of visually representing dynamic intellectual constructions. Throughout the entire history of Russian photography in the first half of the twentieth century, Alexander Rodchenko is the only figure to have left us exclusive traces through the publication of articles and diaries: they are the artistic reflections of a thinker-photographer, the witness to a historic cataclysm that generated a tragic conflict in him between conscious supposition and the unconscious creative drive.
