My dissertation explores the science of nutrition in Britain in the first half of the 20th century. Archival research in the United Kingdom led me to explore further the Anglo-American connections related to the science of nutrition, and ask how American philanthropy came to shape the European scientific community working on public health. The Rockefeller Foundation (RF) was the single most influential American organization in the establishment of British nutritional labs, particularly those in Cambridge, and was also involved in educational programs in fields related to nutrition: agriculture, natural sciences and bio-chemistry. Many of the key figures I study in my dissertation, such as Harriet Chick, Clemens von Pirquet, and Robert Leiper, were supported by the Rockefeller Foundation. Understanding the nature of those American-European and American-British connections is a crucial part of my dissertation and will hone my contribution to the field of interwar internationalism and science.
