Alexander Ernst Fesca was a German composer and pianist. Fesca received his first lessons from his father and made his debut at the age of 11 as a pianist in his hometown. At the age of 14 he graduated in composition at theRoyal Academy of the Arts in Berlin. His teachers included August Wilhelm Bach (1796–1869), Wilhelm Taubert (1811–1891) and Carl Friedrich Rungenhagen (1778–1851). In 1838, he returned to Karlsruhe. He got his first success with the operetta "Mariette" in the same year. Fesca was known during his short life mostly through his songs and piano pieces in which his talent is coupled with a certain musical lightness. This is probably also the reason why some music scholars deny "deeper level" and "artistic seriousness" of his works. In 1841, his opera "The French in Spain" was staged with great success. In the same year, Prince Egon von Furstenberg appointed Fesca as Chamber Virtuoso. From 1842, he settled in Brunswick. In the local court theater on 25 July 1847 was premiered Fescas major work, five-act heroic-romantic opera "Il Trovatore" with a libretto by Frederick Schmetzer. On 22 February 1849, Alexander Ernst Fesca, aged 28, died of lung disease in Braunschweig.
