(Quase) anônimos: colaboradores do Escritório Técnico Samuel das Neves no início dos anos 1910

The presence of collaborators in engineering and architecture offices is an insufficiently researched subject, most of which remain unknown even in specialized publications. This paper analyzes the participation of some professionals in Samuel das Neves Technical Office (Escritorio Tecnico Samuel das Neves) during the first two decades of the 20 th century, especially about works related to the State Penitentiary Competition (Concurso da Penitenciaria do Estado) and to Sao Paulo’s Master Plan (Plano Melhoramentos) . Most of them were foreigners with extensive professional knowledge and who worked at the Sao Paulo headquarters of the company in its best known and commented period: Carlos Escobar, Giulio Micheli, Giuseppe Sacchetti, A. Maurice de Ladriere, Jose Talarico, and Giacomo Corberi.
