To sanitize is to eugenize: the “preventive” eugenics of Belisário Penna at the service of sanitation in Brazil, 1920-1930

Abstract

The purpose of this article is to discuss the eugenics model used by the medical-sanitarist Belisário Penna during the sanitation campaign in Brazil in the 1920s and 1930s. The article addresses two fundamental concepts for his thinking: “Brazilian race” and “preventive” eugenics. The way in which Penna saw the Brazilian racial issue was fundamental to adhere to the eugenic conception combined with social medicine and its project of “health awareness.” The text offers a perspective of how Penna’s eugenics was conceived and the dialogue established with the Brazilian eugenic movement, especially with the eugenicist Renato Kehl. Thus, the defense of an eugenics classified as “preventive” established a coherence for a social reform project through the sanitation defended by Penna.
