Samuel Barnsley Pessoa Collection \/ S\u00e9rgio Buarque de Holanda History Research Support Center-USP<\/span><\/a> Samuel Pessoa\u2019s accomplishments put him at the forefront of medical parasitology and rural public health in BrazilSamuel Barnsley Pessoa Collection \/ S\u00e9rgio Buarque de Holanda History Research Support Center-USP<\/span><\/p><\/div>\n

The settlement of rural S\u00e3o Paulo State, prompted by the late nineteenth-century expansion of the coffee industry, played a hand in the erosion of living conditions in the countryside and the outbreak of a number of epidemics. Some doctors ascribed these problems to Brazil\u2019s tropical climate, while others cited the absence of government in these regions. But parasitologist Samuel Pessoa believed that a broader approach, grounded in a Marxist perspective, was needed to interpret the situation in the countryside. As he saw it, the ubiquity of disease in agricultural areas was a consequence of the country\u2019s rural economic structure, and large landholdings were key to understanding endemic diseases in agrarian Brazil.<\/p>\n

Pessoa\u2019s work as a physician, professor, and Communist militant contributed to the institutionalization of teaching and research in medical parasitology and rural public health in Brazil, at a time when research into the diseases afflicting Brazilians in the countryside overlooked people\u2019s living conditions. The public now has access to documents that Pessoa amassed over the course of his career, at the S\u00e9rgio Buarque de Holanda History Research Support Center, of the University of S\u00e3o Paulo (USP). The collection holds over 2,500 items, including articles, letters, and photographs, all organized and digitized by historian Aline Lacerda, with the Oswaldo Cruz Foundation (Fiocruz) in Rio de Janeiro.<\/p>\n

Samuel Barnsley Pessoa (1898-1976) was born in S\u00e3o Paulo. In 1916, he entered the newly founded S\u00e3o Paulo School of Medicine and Surgery, which was to become one of the cornerstones of USP when the university was established in 1934. The medical school was then negotiating with the Rockefeller Foundation about funds for conducting research work and installing a public health laboratory at the institution, made possible under an agreement signed in 1918. Given that the treatment and prevention of ancylostomiasis lay at the center of the foundation\u2019s concerns in Latin America, it was no coincidence that Pessoa presented a paper on the illness as his medical school graduation thesis in 1922.<\/p>\n

That same year, Pessoa received a Rockefeller Foundation grant to conduct work at health clinics in the interior of S\u00e3o Paulo and study endemic diseases in agricultural regions. \u201cIt was then that he became familiar with the reality of S\u00e3o Paulo\u2019s rural populations and first observed signs of the tacit relationship between large landholdings, poverty, hunger, and rural endemic diseases,\u201d says political scientist Gilberto Hochman, of Fiocruz, who studied the physician\u2019s archives before they were made available to the public.<\/p>\n

At the age of 33, Pessoa took what was then one of the top positions in medical teaching and research in Brazil: professor of medical parasitology at the S\u00e3o Paulo School of Medicine and Surgery. He trained several generations of scientists, among them parasitologists Luiz Hildebrando Pereira da Silva, who died in 2014; Ruth and Victor Nussensweig; and Erney Plessmann de Camargo. \u201cPessoa always demanded that his collaborators be socially engaged,\u201d says Camargo, researcher at the USP Biomedical Sciences Institute (ICB). \u201cHe chided me more than once for being more concerned with basic research than research applied to public health.\u201d<\/p>\n

Appointed head of the S\u00e3o Paulo State Directorate of Public Health in 1942, Pessoa decentralized the state\u2019s public health administration, granting local government greater autonomy in the control of rural diseases. He held the post until 1944, when he returned to USP. His career as a doctor and professor ran parallel to major political events, such as the Revolution of 1932, the Estado Novo dictatorship (1937-1945), and World War II (1939-1945). Infected by the political excitement of the day, he joined the Communist Party of Brazil (PCB).<\/p>\n

According to Hochman, Pessoa helped shape a genuinely Brazilian field of knowledge. His research on the public health conditions of people in Northeast Brazil underpinned the establishment of the National Malaria Service, which was the embryo of the National Department of Rural Endemic Diseases (DNERu). \u201cWith his assistants, he studied the vectors of Chagas disease, leishmaniosis, and schistosomiasis<\/em> throughout Brazil,\u201d says Camargo. \u201cIn S\u00e3o Paulo, his research helped guide the Malaria Prophylaxis Service, founded in 1943.\u201d Pessoa published 352 scientific papers, more than 50 newspaper articles, and 9 books, including Parasitologia m\u00e9dica<\/em> [Medical parasitology], released in 1946. The book became mandatory reading at all medical schools in Brazil, and revised editions were published until 1982.<\/p>\n

In 1952, the parasitologist was invited to join the committee responsible for investigating whether the United States had deployed biological weapons in the Korean War. The panel produced a 600-page document confirming that the country had done so. \u201cPessoa\u2019s role in this episode earned him tremendous public visibility,\u201d says Hochman. \u201cIt cost him legal battles and persecution by the political police and won him adversaries inside the Rockefeller Foundation and the Brazilian medical community,\u201d the researcher explains. After retiring from USP in 1956, Pessoa traveled extensively around Brazil, offering undergraduate courses and organizing research centers in Alagoas, Sergipe, Bahia, Para\u00edba, and other states into the mid-1970s.<\/p>\n","protected":false},"excerpt":{"rendered":"Samuel Pessoa helped forge an intellectual tradition of public health ","protected":false},"author":346,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"_exactmetrics_skip_tracking":false,"_exactmetrics_sitenote_active":false,"_exactmetrics_sitenote_note":"","_exactmetrics_sitenote_category":0,"footnotes":""},"categories":[152],"tags":[241,247],"coauthors":[662],"class_list":["post-250034","post","type-post","status-publish","format-standard","hentry","category-retrospect","tag-history","tag-medicine"],"acf":[],"_links":{"self":[{"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/posts\/250034","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/users\/346"}],"replies":[{"embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/comments?post=250034"}],"version-history":[{"count":0,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/posts\/250034\/revisions"}],"wp:attachment":[{"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/media?parent=250034"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/categories?post=250034"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/tags?post=250034"},{"taxonomy":"author","embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/coauthors?post=250034"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
