Photograph of JUAN NCREVANI (1877–1947), Chilean microbiologist of Italian origin. In 1902, Noé Crevani obtained a degree in medicine at the University of Pavia, Italy, where he was a disciple of Giovanni B. Grassi, discoverer of the role of the Anopheles mosquito in the transmision of human malaria. In 1912, he accepted a position at the Faculty of Medicine of the University of Chile, Santiago, specializing in parasitic infectious diseases and profoundly influencing both medical research and sanitation conditions in Chile. Noé Crevani worked tirelessly against malaria, which was erradicated from Chile by his collaborators in 1952, a few years after his death. He also studied other major endemic parasitic diseases, including anchilostomiasis, caused by the helminth Ancylostoma duodenalis, and Chagas disease, caused by the protist Trypanosoma cruzi. At his death, he left behind an important school of physicians, microbiologists, and researches in his adopted country.
