António Egas Moniz
António Caetano de Abreu Freire Egas Moniz (29 November 1874 – 13 December 1955), known as simply Egas Moniz, was a Portuguese neurologist and the developer of cerebral angiography. He is regarded as one of the founders of modern psychosurgery, having developed the surgical procedure leucotomy—better known today as lobotomy—for which he became the first Portuguese national to receive a Nobel Prize in 1949 (shared with Walter Rudolf Hess).
