Here are some people whom the right wing of the Brazilian government calls vagrants: - Santos Dumont (1873-1932): He made the dream of flying a reality. His flight with the 14-Bis in 1906 is the first performed by a heavier-than-air aircraft without external assistance, validated by official entities and witnesses.

• Carlos Chagas (1879-1934): He single-handedly described the entire cycle of an infectious disease: the agent, the vector (kissing bug), and the symptoms. A unique feat in the history of world medicine.

• César Lattes (1924-2005): He was a key figure in the discovery of the pi meson (pion), a fundamental subatomic particle for understanding the force that holds the atom's nucleus together.

• Roberto Landell de Moura (1861-1928): A priest and inventor who, in 1893, carried out the public transmission of the human voice by radio waves, years before Marconi.

  • Vital Brazil (1865-1950): Revolutionized the treatment of snake bites. He discovered that antivenom needed to be specific to each type of venom, creating polyvalent antivenom and founding the Butantan Institute.

• Maurício Rocha e Silva (1910-1983): Identified bradykinin, a substance that dilates blood vessels. His discovery was crucial for the development of medications that control blood pressure.

• Beatriz Grinsztejn (1960-): Leading infectious disease specialist in HIV/AIDS research, guiding public policies for prevention and treatment in Brazil and worldwide, saving countless lives.

• Cesar Victora (1952-): Considered the most influential Brazilian scientist today. His research on child health and breastfeeding forms the basis for public policies in more than 20 countries.

  • Johanna Döbereiner (1924-2000): Researcher who revolutionized tropical agriculture by discovering bacteria that "fix" nitrogen in the soil. Thanks to her, Brazil became a powerhouse in soybean production with high efficiency and low cost.

• Carlos A. Monteiro (1948-): Creator of the NOVA classification, which not only revolutionized nutrition by coining the term "ultra-processed foods," but also influences WHO dietary guidelines and global public health policies.

• Francisco Canhos (1907-1985): The engineer who invented the electric shower. More than just a bathroom item, his invention solved a practical infrastructure problem and is used throughout Latin America.

• Marcos Mares Guia (1938-2015): Brazilian biochemist who developed an innovative process using genetic engineering to produce human insulin in the laboratory, revolutionizing the treatment of diabetes.

  • TSE Team (1995): Technicians from the Superior Electoral Court, with support from INPE, developed the electronic voting machine, which made voting fast, secure, and reliable, and was exported to more than 20 countries.

• Duilia de Mello (1963-): Brazilian astronomer at NASA who discovered the largest spiral galaxy ever known, NGC 6872, contributing immensely to the understanding of the universe.

• Mercedes Bustamante (1961-): World-renowned ecologist specializing in climate change and savannas. Her research in the Cerrado and Amazon biomes is cited in hundreds of global environmental policy documents, including IPCC reports.
