1843–1910
An Italian writer and teacher from Milan, he brought together patriotism, scholarship, and a strong interest in Sicily’s history and culture. His best-known work, Le tre valli della Sicilia, reflects the broad historical and civic themes that shaped his life.

by Gaetano Sangiorgio
Born in Milan on September 15, 1843, Gaetano Sangiorgio was the son of the sculptor Abbondio Sangiorgio and Antonia Pusterla. A biographical note preserved by Liber Liber says his classical studies were interrupted in 1860 by his participation in Garibaldi’s campaign in Sicily and at Capua, after which he resumed his education in Pavia, where he studied law at the Collegio Borromeo.
That same source describes a varied career: he taught in secondary schools and technical institutes, worked in journalism, and wrote on history, geography, and public questions. It also notes that he collaborated with the review L'Esploratore; a separate archival record from the University of Milano-Bicocca identifies him as a member of the Società d’Esplorazione commerciale in Africa.
Readers today are most likely to encounter him through Le tre valli della Sicilia, a work available through Project Gutenberg and other digital libraries. The dates attached to him vary across library and archive records, with some sources listing 1843–1910 and others 1843–1912, so the exact year of his death is not entirely consistent in the sources I found.
