António Caetano de Abreu Freire Egas Moniz

Egas Moniz (1874–1955) was a Portuguese neurologist and the pioneer of the lobotomy procedure, which he developed based on experiments with chimpanzees. His controversial technique aimed to treat mental illnesses by severing connections in the brain, particularly in the frontal lobe. Moniz was awarded the Nobel Prize in Physiology or Medicine in 1949 for his work, which has since been widely criticized for its ethical implications and long-term consequences for patients.
