Controlling the Field: Memory, Labor, and Ethics in Oral Histories of Brazilian Human Genetics

Berichte zur Wissenschaftsgeschichte, EarlyView.
This article examines how oral histories of twentieth‐century human genetics in Brazil reveal the politics of memory of fieldwork. Through a comparative analysis of interviews with prominent geneticist Francisco M. Salzano and technician Girley V. Simões, who worked with him for most of his career, this study explores the narrative strategies each ...
