[Eliasz Cynamon and the Rio Doce Program (SESP): contribution of sources to the history of health and sanitation actions in Brazil, 1952-1960].

Research into the work of Szachna Eliasz Cynamon in the Rio Doce Valley Program (1952-1960) is presented. The key sources are from the Department of Archives and Documentation and the Department of Sanitation and Environmental Health at Fiocruz, as well as the family's own archive. At the time, the rates of malaria in the region were high. Born in Poland, Cynamon migrated to Brazil in the 1930s while still a child, where he graduated in sanitary engineering. He was hired to work in Colatina (Espírito Santo) and Governador Valadares (Minas Gerais) between 1952 and 1960, focusing on sewage and water treatment and supply, while also holding sanitation education courses for the local people as part of a Brazil-USA cooperation agreement.
