In 1966, a team made up of Brazilian and foreign scientists spent a week carefully recording the body temperature and other clinical signs and symptoms of 110 Tiriyó Indigenous people in their communities along the Brazil-Suriname border. Led by the Yale University virologist and immunologist Francis Black, the researchers faced an "epidemic" with a special profile, distinct from those most common in Indigenous populations, which usually resulted in widespread illness, the collapse of subsistence activities, hunger, and as a rule, elevated (...) mortality.Rather, what was happening with the Tiriyó was a planned event, controlled and carefully...

In 1962 a team of scientists conducted their first joint fieldwork in a Xavante village in Central Brazil. Recycling long-standing notions that living Indigenous people represented human prehistory, the scientists saw Indigenous people as useful subjects of study not only due to their closeness to nature, but also due to their sociocultural and political realities. The geneticists’ vision crystalized around one subject – the famous chief Apöwẽ. Through Apöwẽ, the geneticists fixated on what they perceived as the political prowess, impressive (...) physique, and masculine reproductive aptitude of Xavante men. These constructions of charismatic masculinity came at the expense of recognizing how profoundly colonial expansion into Mato Grosso had destabilized Xavante communities, stripping them of their land and introducing epidemic disease. The geneticists’ theorizing prefigured debates to come in sociobiology, and set up an enduring research programme that Apöwẽ continues to animate even four decades after his death. (shrink)

Twentieth-century field research in the human sciences has repeatedly rendered specific communities and people as subjects of study. As scientists layered field upon field in the same spaces, subjects have gained their own forms of expertise. This essay examines the history of research in Terra Indígena Pimentel Barbosa, in what is now Central Brazil, to argue that fields are composed of human relations and that historians of science have the moral responsibility to recognize that fields are almost always someone’s home. (...) As we constitute our own fields, we accrue obligations of reciprocity, both with the scientists we study and with the communities that were their subjects. To study the past, we must attend reflexively to the futures we make possible. -/- . (shrink)
