Italian operatic composer, born at Majolati; settled in Paris in 1803, and a year later made his mark with the little opera "Milton," and subsequently established his fame with the three grand operas, "La Vestale," "Ferdinand Cortez," and "Olympia"; from 1820 to 1842 was stationed at Berlin under court patronage, and in the face of public and press opposition continued to write in a strain of elevated and melodious music various operas, including his greatest work "Agnes von Hohenstaufen" (1774-1851).
