he faced in Brazil, from some physicians and researchers of that time. They went as far as questioning the existence of Chagas disease, thereby possibly influencing the decision of the Nobel Committee not to award the prize to him. Analysis of the database of the Nobel Prize archives, with the revelation of the names of nominators, nominees, and prizewinners from 1901 to 1951, brought information not only about what was considered to be a scientific achievement at that time, but also about who the important scientists were and the relationships between them. The connections of the members of the Nobel Committee with the international scientific community, almost exclusively centered in European and North American scientists, also influenced their choices. The nonrecognition of Carlos Chagas' discoveries by the Nobel Committee appears to be more correctly explained by these factors than by the negative impact of the local opposition.
