Francesco Fausto Nitti (born 2 September 1899 in Pisa – died 28 May 1974, in Rome) was an Italian journalist and fighter against fascism. His father Vincenzo (1871–1957) was evangelical preacher of the Italian Methodist Church. His mother was Paola Ciari (1870–1932).
When Francesco Fausto Nitti was seventeen, he fought in the First World War. In 1924, after the death of Giacomo Matteotti (a socialist deputy killed by will of Benito Mussolini), Nitti started an active anti-fascist propaganda, and as a result in December 1926 he was arrested and confined in Lipari. Along with two other political prisoners, Carlo Rosselli and Emilio Lussu, he managed to escape in July 1929 and to take refuge in France, where they founded Giustizia e Libertà, a resistance movement opposing fascism.
Nitti went to Spain in March 1937 and served the Republican faction as a major during the Civil War. After the defeat of his side, he came back to France where was relegated in a concentration camp and later sent on the Nazi Ghost Train in order to be deported in Germany; Nitti (as well as one hundred of the seven hundred prisoners) fled when the train was near the German frontier, after removing some planks from the floor of his wagon.
He returned to France and joined the maquis, helping the French Resistance. After rejoining his family at Tolosa, in 1946 he eventually returned to Italy. Taking a variety of roles in anti-fascist associations, he was director of the Anpi- based review “Independent Native land” and became a commune councilman in Rome.
Nitti died in Rome on May 28, 1974.
