Gaetano De Sanctis

De Sanctis became chair of ancient history desk at the University of Rome in 1929. In 1931, he was one of only twelve professors who refused to swear a decreed oath of allegiance to the Fascist regime (Giuramento di fedeltà al fascismo) under Benito Mussolini. As a result, his professional career was severely curtailed until after World War II.
He was governing commissar of the Italian Numismatic Institute from 1944 to 1952 and president of the "Istituto dell'Enciclopedia Italiana" (Treccani) from 1947 to 1954. He was elected to the American Philosophical Society in 1946.
Gaetano De Sanctis is considered by many as the most eminent Roman historian of the twentieth century. Provided by Wikipedia
