In presenting the significant influence of Richard Neutra over Harwell Hamilton Harris and the way Harris’ legacy affected Gordon Drake’s work, a modern genealogy spanning three generations of California architects –from the mid-20s to late 40s– is established on this thesis to discuss how these authors understood and expressed their special links with the physical environment and the creative landscape of Southern California. The analysis of the buildings and projects in which these architects worked together as disciples and masters and, above all, the identification of their circles of influence, can describe some of the formative events that best explain the channels through which the most original modern traditions in the region were generated and transmitted. Harwell Hamilton Harris and Gordon Drake are two genuine California architects. Despite the quality of their work, it remains quite unknown to the European architectural culture. This situation is representative of how the history of modern architecture has approached California only through a few incomplete reports whose main sources should be furthermore examined. This is the case of Esther McCoy, the first architectural historian of the California modern period whose writings are often quoted without considering her frequent personal involvement in the very facts that she describes. Harris reached Neutra’s office in 1928. Richard Neutra was by then living at Pauline and Rudolph Schindler’s home in Kings Road, where he was completing the executive project of the Lovell House, the building to which Neutra devoted the most important promotional effort in his career and the work that confirmed his international celebrity. Just over a decade later, Gordon Drake joined Harris’ office where he worked in fact on the Weston Havens House project. This house assured the recognition to his mentor. The Weston Havens House was completed some weeks before the US entry into World War II. The cover of March 1940 issue of California Arts & Architecture portraying full-page the inspired cross-section of this house meant a turning point in Harris’ career and equally decisive for John Entenza. For the architect it entailed the end of his relationship with the magazine. Regarding the editor, it was his first cover and the beginning of a thriving publishing career oriented to make prestige. Meanwhile, Drake won with his first work, his own home in Los Angeles (1946), the first contest of Progressive Architecture magazine. The photographs that Julius Shulman took of Drake’s house catapulted him to fame. The architect was a young promise whose meteoric career was suddenly interrupted by an accident that cost him his life before turning 35 years old. The Media interest aroused by the work of these architects brings the opportunity to explore the mechanisms of fame and the editorial policies of the time, as well as the publicity strategies of these authors and even the importance that some protagonists of these stories conceded to the elaboration of their own biography. This thesis insists on the important of the construction of the affections and relationships that made possible those architectures. In this sense the militant commitment of Pauline Schindler was vital. Throughout her life, she mobilized a network of architects, artists, photographers, writers, political activists, intellectuals and progressive clients without whose friction the history of California modern architecture would have probably been quite another matter.
