This PhD dissertation explores in depth the work of Marcel Breuer, looking for his origins in his time at the Bauhaus, in which he participates as student and master, and try to discover like the pedagogical practice of artists as Itten, Klee, Kandinsky, Albers, Moholy-Nagy and Gropius especially, those who manifest connection and affinity, and to what extent contributed not only to the training of Marcel Breuer, but also how it can be recognized in his later work. We will discover a glimpse of other presences, in some cases will be more tangential, or temporary as the case of the work and thought of Le Corbusier, Mies and Hilberseimer, and in other cases will be after his process of training, during his maturity, specific contacts that will leave in Breuer a print that will mark his later architecture, as it is the case of his collaboration with the Italian engineer Pier Luigi Nervi. It is of special interest, perceive how the formal investigation of it, will discover in latent state the returns to the origin, relationships that will enable us to comprise the real and immense contribution of this creator to the architecture. Breuer's work is analyzed from a holistic and systemic point of view, as a whole based on all interrelated scales and looking on the value of his mature work beyond the domestic architecture and his furniture design. Thus, to investigate its process of ideation, laying the necessary bases on which it is based, gives us the opportunity to analyze, study and deepen a work as extensive as varied in typologies, with a very personal character, and we will put special interest in research through his learnings, growth, design process, thinking, roots and connections.
