The architectural field has performed a central mediating function in the process of formation of the Brazilian State through the formulation of mechanisms for control, ordering, and management of territories and populations. In the present article, we address three different scenarios in which architectural professional networks played a significant role: national-developmental projects implemented from the 1930s onwards; housing policies developed during the military dictatorship (1964 to 1985); strategic plans for the production of “global cities” following the redemocratization process (1985-today). From among the kaleidoscope of professional practices and meanings mobilized during these periods, we highlight situations and events that triggered the ideal types of the “creative genius”, the “engaged anti-designer” and the “entrepeneurial manager”. By analyzing the interactions between architects and public administration, we hope to contribute to the understanding of the population management technologies and business mechanisms that supported the neoliberal turn in the forms of government in Brazilian cities.
