First one of the impulses in the present investigation, happens for checking the superficial judgment to which there was submitted the architectural Valencian production of beginning of the 20th century. Removed from the initiation centers European, succumbed relegated to the bipolar argument, national discussion Madrid - Barcelona, without reaching merits for a sharp architectural analysis. To try light to similar occlusion appears as aim. To investigate sources, to catalogue and to systematize the thickness of the racionalist Valencian production, it states the change in the taste of the young architects, as approximation to the modernity. It remains to make concrete a doctrinal coherence and the social commitment praised by the teachers of the Modern Movement. To generalize exhibits a white of egg lacking in commitment and, in order such a lack of attention stays away, an author splits, Luis Albert Ballesteros with the purpose of confirming his racionalist determination. To re-draw original mappings, to recreate schemes, perspectives, details and to shape models, it turns out to be the used method. To recreate the graphical analysis as tool to the depth of the knowledge, he returns the analytical look to an individual production. The metropolis, relating aspiration of modernity, explains the physical area of this work. The whiteness of Albert's architecture, a National Competition for the Ateneo Mercantil of Valencia, marks the chronological low limit. The Superior, does not admit disjunctive arguments, The Civil War assumes the unavoidable border. Luis Albert stands out between the promoters of the racionalist intention, in the capital of Levante, immersed in the sleepless night Spain of the twenties and thirties. His contributions leave evidences of his spirit trasgresor towards the doctrines historicist of the Academy, his zeal of professional renovation and his sincerity representation. His proclaimed way of the truth, occupied in creating pure lines and harmonious volumes, in promoting the usefulness of the constructed and attacking the modern space, well costs to try the pass to his contributions in the catalogues of the modern architecture. 395
