After submitting my doctoral thesis, I studied documents on public health research in colonial India at the Rockefeller Archive Center (RAC). The visit, from the end of September to early December 2019, allowed me to expand my research on medical infrastructure and sanitary regulations in colonial India. My thesis looked at the sanitary interventions by the British colonial state and Christian missionaries in British Indian port cities in the nineteenth century for protecting the health of European seamen. In my follow-up research, I wanted to explore the development of the study of health and disease in the twentieth century. The governance of public health in this phase was arguably driven by new explorations into bacteriology and virology in various institutes across India. The Rockefeller Foundation (RF) was substantially involved in many of these disease research centers as part of its global fight for public health. It was instrumental in establishing the All-India Institute of Hygiene and Public Health (AIIHPH). As a scoping study for my pile-up project on public health in the first half of the twentieth century, I read reports and correspondence regarding the planning and early years of the institute. I spent a highly fulfilling two months with the RAC, reading important documents on the RF's medical philanthropy and its role in shaping public health research in British India. The stint also enabled me to connect with researchers working on similar subjects.
