Nina Rodrigues and the madness of crowds

Abstract

This text is aimed to analyse an underexplored set of documents related to the research referring to the physician Raimundo Nina Rodrigues on collective phenomena recorded between the late nineteenth and early twentieth centuries. We intend to emphasize some reflections of that author and especially the dialogue which he established with foreign professionals in the field of sociology, anthropology and mental health. Nina`s intellectual effort is like a witness of the birth of a field of study whose first lines were being drawn in Brazil: crowd psychology or the madness of crowds. Nina rescues a rich tradition of studies to address, in its way, cases of collective and religious epidemics in Brazil, linked to the black and miscegenated population.
