1. Oswaldo Cruz (1872–1917)

Oswaldo Cruz, born in 1872 in São Luis do Paraitinga, São Paulo, emerged as a pioneering figure in Brazilian public health. The son of a physician, he was naturally drawn to the medical field, moving to Rio de Janeiro, where he would eventually revolutionize public health practices. His education at the Faculty of Medicine of Rio de Janeiro and later specialization in bacteriology at the Pasteur Institute in Paris set the foundation for his illustrious career in combating infectious diseases in Brazil.

Cruz’s return to Brazil began an aggressive campaign against the bubonic plague, yellow fever, and smallpox, utilizing modern epidemiological methods. His leadership at the Federal Serum Therapy Institute later renamed the Oswaldo Cruz Institute, was instrumental in producing vaccines and sera to combat these diseases. Despite facing significant opposition, his sanitation and public health campaigns dramatically reduced the incidence of these deadly diseases in Rio de Janeiro and beyond, earning him national and international recognition.

Cruz’s legacy extends beyond his death in 1917, leaving an indelible mark on Brazilian medicine and public health. His work eradicating yellow fever and improving sanitation standards transformed Rio de Janeiro into a safer city, saving countless lives. The Oswaldo Cruz Institute continues to be a leading center for medical research in Latin America, a testament to Cruz’s lasting impact on the field of medicine and public health in Brazil.

2. Carlos Chagas (1879–1934)

Carlos Chagas was born on July 9, 1879, in Oliveira, Minas Gerais, Brazil, into a family of Portuguese descent. His father, a coffee farmer, passed away when Carlos was just four years old, setting the stage for a challenging childhood. Despite these early obstacles, Chagas was propelled into the medical field by his family’s circumstances and his uncle’s influence, ultimately steering him toward a career that would leave a lasting impact on public health and medicine in Brazil and beyond.
