Justice where justice is due: A posthumous Nobel Prize to Carlos Chagas (1879–1934), the discoverer of American Trypanosomiasis (Chagas' disease)

Working in the Brazilian backland, Chagas described a new disease. He discovered the etiologic agent, the vector, the reservoir, the acute stage, the several clinical aspects of the chronic stage (particularly the heart disease), role of autoimmunity in its pathogenesis, and anticipated the social impact of the disease. Chagas was nominated to Nobel Prize twice: in 1913, and in 1921. In 1913, Richet won the prize because his work on anaphylaxis. In 1921, no one received the Nobel Prize. It is believed that detraction of Chagas' work at the National Academy of Medicine, made by jealousy, mediocrity, and political rivalries can be maculated the image of the scientist. Furthermore, misperception of Chagas' work may also have led the Nobel Committee not to award him. One-hundred years after the discovery, we can appreciate the greatness of the discovery of Carlos Chagas, never seem in the realm of biological research. Time to make justice, therefore, has finally come.
