Umberto Giordano (August 28, 1867 - November 12, 1948) was an Italian composer, mainly of opera. He was born in Foggia in Puglia, Italy and studied under Paolo Serrao at the Conservatoire of Naples. His first opera "Marina", was written for the competition staged by the music publishers Casa Sonzogno for the best one-act opera, remembered today because it marked the beginning of Italian "verismo"; the winner was Mascagni's "Cavalleria Rusticana".
