Egas Moniz


(António Caetano de Abreu Freire) Egas Moniz was born in Avanca, Portugal, on November 29, 1874, the son of Fernando de Pina Rezende Abreu and Maria do Rosário de Almeida e Sousa. He received his early education from his uncle Abbé Caetano de Pina Rezende Abreu Sa Freire, before joining the Faculty of Medicine at Coimbra University. He received further education at Bordeaux and Paris and became Professor at Coimbra in 1902. In 1911 he transferred to the new Chair in Neurology at Lisbon where he remained until his death. He also worked for a time as a physician in the Hospital of Santa Maria, Lisbon.

Moniz entered politics in 1903 and served as a Deputy in the Portuguese Parliament until 1917 when he became Portuguese Ambassador to Spain. Later in 1917 he was appointed Minister for Foreign Affairs and he was President of the Portuguese Delegation at the Paris Peace Conference in 1918.
