Italian author of letters and of lyric and autobiographical novels.

Comisso earned a law degree at the University of Siena but never worked as a lawyer. He served in World War I, then lived in Fiume, Italy (now Rijeka, Croatia), with Gabriele D'Annunzio (D'Annunzio, Gabriele), operated a bookstore in Milan, and was an art dealer in Paris. While working for the major Italian newspapers La gazzetta del popolo, Corriere della sera, Il messaggero, and La stampa, Comisso traveled extensively in Italy and abroad. He then collected and published his letters in volumes by subject: his letters from Paris in Questa è Parigi (1931; This Is Paris); from the Far East in Amori d'Oriente (1949; Loves of the Orient), Cina-Giappone (1954; China-Japan), and Donne gentili (1959; Kind Women); from Italy in Un italiano errante per l'Italia (1937; An Italian Roaming Italy), La favorita (1945; The Favorite), and La Sicilia (1953; Sicily); and from Europe in Viaggi felici (1949; Happy Journeys) and Approdo in Grecia (1945; Landing on Greece).

After World War II Comisso worked for the newspapers Il mondo, Il giorno, and Il gazzettino. Among his award-winning fiction are Capricci italiani (1952; Italian Whims) and Un gatto attraversa la strada (1955; A Cat Crossing the Street; winner of the Strega Prize).
