Peter Cornelius, also known as Carl August Peter Cornelius, (24 December 1824 – 26 October 1874) was a German composer, writer about music, poet and translator. He was born and died in Mainz where his grave in the Hauptfriedhof survives. Cornelius played violin and composed lieder from an early age, and began studying composition with Heinrich Esser in 1841. Cornelius lived with his painter uncle Peter von Cornelius in Berlin from 1844 to 1852, during which time he met prominent figures such as Alexander von Humboldt, the Brothers Grimm, Friedrich Rückert and Felix Mendelssohn. During his last few years in Berlin, Cornelius wrote music criticism for several major Berlin journals and entered into friendships with Joseph von Eichendorff, Paul Heyse and Hans von Bülow. Cornelius's first mature works (including the opera Der Barbier von Bagdad) were composed during his brief stay in Weimar (1852–1858). His next place of residence was Vienna, where he stayed for five years. It was in Vienna that Cornelius began a friendship with Richard Wagner. It was at Wagner's behest that Cornelius moved to Munich in 1864, where he finally took a wife and fathered four children. Among many British musicians, his best known work is "The Three Kings", an epiphany 'carol' of which a version is included in the first volume of the popular Willocks and Jacques compilation, Carols for Choirs. Despite his friendships with Wagner and Franz Liszt, Cornelius had a rocky relationship with the so-called "New German School" of composition. He did not attend the premiere of Tristan und Isolde with von Bülow and Wagner, using the premiere of his own opera Der Cid as an excuse. His third and final operatic project, Gunlöd, based on the Norse eddas, was left incomplete at his death (from diabetes).
