Prophet in his own country: Carlos Chagas and the Nobel Prize.

Abstract

In 1909, Carlos Chagas (1878-1934) discovered a new protozoon, Trypanosoma cruzi, and the (previously unknown) disease that it causes. Within a few months, virtually single-handed, he described the pathogen, its vector, and the clinical features of American trypanosomiasis (Chagas disease), a feat unique in medical history. He headed the Oswaldo Cruz Institute after the death of its founder (1917) until his own death; and from 1920 until 1926 he also directed the Brazilian Department of Public Health. His discovery brought him worldwide acclaim, but at home antagonism against Chagas, muted for years, finally flared up in a campaign that was acted out in the 1921-22 plenary sessions of the National Academy of Medicine. Chagas's name was repeatedly proposed for the Nobel Prize but he never received it; this hostile campaign may have been instrumental in costing him the award.
