Carlo Orelli (December 23, 1894 – January 22, 2005) was, at age 110, the last surviving Italian World War I veteran who joined the army at the onset of the war. Born in Perugia, although he lived in Rome for most of his life, Orelli came from a military family whose members had served in various Italian conflicts since 1849. A mechanic by trade, Orelli joined the Italian Army in May 1915 and engaged in combat operations in Italy.
