Sadí de Buen, the doctor who promoted the largest campaign against malaria in Spain who was shot by Francoism

On September 2, 1936, Sadí de Buen, a prominent Spanish epidemiologist who led one of the most significant anti-malaria campaigns in Spain during the early 20th century, was executed by firing squad in Córdoba along with nine others. De Buen had been working to eradicate malaria through scientific methods such as strict epidemiological control, free distribution of quinine, and public education, supported by international aid including the Rockefeller Foundation. His efforts nearly eliminated the disease before the Spanish Civil War disrupted progress. De Buen was targeted due to his Republican and leftist affiliations, and he was executed without trial. He came from a family of intellectuals and scientists, many of whom were later exiled or died abroad. His work laid the foundation for modern public health initiatives in Spain.

On the night of September 2, 1936, Sadí de Buen and nine others were executed in Córdoba, near the walls of San Rafael cemetery. Among them were two bricklayers, a painter, and two laborers. According to historian Manuel Chaves Nogales, they were part of “la España fusilable”, those deemed politically expendable under Francisco Franco’s regime. De Buen, an inspector general of Health for the Republican government, had been detained on July 22 without trial or due process. His political affiliations and family background made him a target of the regime’s purges. Sadí de Buen Lozano was one of the key figures behind Spain’s most significant public health campaign of the early 20th century: the fight against malaria. Between 1920 and 1936, a small group of individuals, guided by scientific and social medicine principles, nearly eradicated the disease. Their efforts marked a turning point in Spanish public health, though the devastation of the Spanish Civil War reversed these gains within three decades. The campaigns relied heavily on international support. Before the war, the anti-malaria initiative was the only major public health project endorsed by the Rockefeller Foundation, indicating its perceived effectiveness and alignment with global health standards. Historian Esteban Rodríguez Ocaña notes this external validation as a reflection of the Spanish healthcare system's strengths during that period. Born in Barcelona in 1893, Sadí de Buen was the third of six children of Odón de Buen, a professor who founded the Spanish Oceanographic Institute in 1914. He grew up in a progressive environment, attending the modern school of Ferrer i Guardia, under his mother’s care. His parents married civilly in 1889 and did not baptize their children. Four of his brothers, including a lawyer, oceanographers, and another epidemiologist, died in exile in Mexico. His father is honored today by the name of Spain’s largest oceanographic vessel. De Buen studied medicine and quickly specialized in malaria alongside Italian-Spanish physician Gustavo Pittaluga, a prominent figure in Spanish public health. Pittaluga, who later had to flee and died in Havana in 1956, inspired De Buen and others in implementing anti-malaria campaigns. In 1920, shortly after marrying civilly, De Buen began working in Talayuela, Cáceres, the region most affected by malaria. His work focused on controlling the disease through strict epidemiological methods, free quinine distribution, and community education, supported by dispensaries in all affected areas. Malaria historically caused immense loss of life and economic disruption. It weakened workers, leading to lost productivity and widespread suffering. Transmitted by mosquitoes of the Anopheles genus, the parasite enters the bloodstream through bites, causing fever cycles every few days. Symptoms included severe discomfort, headaches, and enlargement of the spleen. By the early 20th century, the national mortality rate stood at around 10 deaths per 100,000 inhabitants, but it steadily declined starting in 1920. By 1936, the rate had dropped to 0.67 per 100,000. However, the Spanish Civil War reignited the crisis, pushing the death rate back up to 6.77 per 100,000 by 1943. This number was ten times higher than in 1926, and it wasn’t until 1949 that the rate fell below pre-war levels.
