(b Lisbon, June 1874; d Lisbon, 1944). Portuguese architect. After completing his studies in architecture (1897) at the Academia de Belas Artes in Lisbon, where he was a pupil of José Luís Monteiro, Machado began his career working as an assistant to Rosendo Carvalheira on Parede Sanatorium (1901), Lisbon. This experience exposed Machado to contemporary styles, particularly the ornamental use of Art Nouveau as expressed in the fine azulejos (glazed tiles) that decorated the sanatorium. His own designs, however, adopted a Romanesque Revival style, for example the mausoleum of the Visconde de Valmôr (1900), Cemitério do Alto S João, Lisbon, which was his first work in this style and showed his preference for compact masses and heavy mouldings. He used similar features in the Colégio Academico (1904), 13 Avenida da Republica, which is one of the most important Romanesque Revival buildings in Lisbon, designed as a heavy circular structure on a corner site, set between two lateral blocks at right angles to each other. The suggestion of Romanesque weight is not, therefore, confined to a superficial application of motifs but is produced by the fundamental organization of the building’s masses. In the Sociedade Nacional de Belas Artes building (1906), 36 Rua Barata Salgueiro, Lisbon, Machado used the same medievalist aesthetic but less effectively, failing to achieve an organic link between the interior, which opens into wide saloons, and the constricted exterior masses. He also used other styles; for example, his unexecuted design for a viaduct (1909) in Avenida Ressano Garcia was influenced by the academic grandiloquence of contemporary French design, whereas a group of houses (1909–11) at Alto Estoril shows a very contemporary approach combining decorative Art Nouveau azulejo panels with a plan that was almost functionalist in layout, forming an early example of Art Deco in Portugal. In several other designs for private houses Machado showed the same tendency to simplify forms, freeing architecture from eclectic ornament, and this is the most significant aspect of his professional achievement.
