Giuseppe Gazzaniga (October 5, 1743 – February 1, 1818) was a member of the Neapolitan school of opera composers. He composed fifty-one operas and is considered to be one of the last Italian opera buffa composers.
Born in Verona, Gazzaniga was initially intended for the priesthood at the urging of his devout parents. He eventually convinced his father to allow him to pursue a career in music and began studies first in Venice and then at the Conservatorio di Sant'Onofrio a Porta Capuana in Naples. While there, he was a pupil of Niccolò Piccinni and Nicola Porpora. Gazzaniga presented his first opera, il Barone di Trocchia, at the Teatro di San Carlo in 1768. He would spend the next several decades writing mostly operas in Italy with the exception of a few trips to Dresden, Vienna, and Prague. His most successful opera was his Don Giovanni Tenorio written in 1787 to a libretto by Giovanni Bertati, possibly an inspiration for the libretto of Mozart's Don Giovanni. His last opera, Martino Carbonaro o sia Gli sposi fuggitivi, was performed at the Teatro San Moisè in Venice in 1801. He also wrote a symphony and three piano concertos.
Gazzaniga is a comune (municipality) in the Province of Bergamo in the Italian region of Lombardy, located about 60 kilometres (37 mi) northeast of Milan and about 15 kilometres (9 mi) northeast of Bergamo.
Gazzaniga borders the following municipalities: Albino, Aviatico, Cene, Cornalba, Costa di Serina, Fiorano al Serio, Vertova.
Traces of human presence in the Bronze Age have been found in Gazzaniga. The first document attesting the existence of a burgh (castle) dates from 476 AD, when the Barbarian king Odoacer ransacked it. In the Middle Ages Gazzaniga was part of the Confederazione de Honio together with neighbouring communes; in 1397 Gazzaniga was destroyed by the Ghibellines, and again by the Guelphs in the next year.
Later Gazzaniga was in the possession of the Republic of Venice. In 1629 Gazzaniga suffered from a plague.
