Scientific expeditions, photography, and documental intent: the Oswaldo Cruz Institute expeditions (1911-1913)

The article analyzes the photographic series produced by the Oswaldo Cruz Institute in reference to scientific expeditions into the interior of Brazil between 1911 and 1913, with a special focus on the one headed by Arthur Neiva and Belisario Penna and on the development of their documentary discourse. It draws out the choices and emphases used in preparing each visual text, expressed both in the material produced during the journeys and in the process of selecting images for publication. The study's quantitative and qualitative analyses of images from the Neiva-Penna expedition uncover a narrative journey that articulates the natural environment, social life, and evidence of the sickly status of residents of the interior to shape a discourse that disseminates the nascent movement to sanitize the sertao regions.
