Ignaz Moscheles

(Isaac) Ignaz Moscheles (German pronun­cia­tion: [ˈig.nats ˈmɔ.ʃɛ.lɛs]) (23 May 1794 – 10 March 1870) was a Bohemian composer and piano virtuoso, whose career after his early years was based initially in London, and later at Leipzig, where he succeeded his friend and sometime pupil Felix Mendelssohn as head of the Conservatoire.

Moscheles was born in Prague to an affluent German-speaking Jewish merchant family. His first name was originally Isaac. His father played the guitar and was keen for one of his children to become a musician. Initially his hopes fixed on Ignaz's sister, but when she demurred, her piano lessons were transferred to her brother. Ignaz developed an early passion for the (then revolutionary) piano music of Beethoven, which the Mozartean Bedřich Diviš Weber, his teacher at the Prague Conservatory, attempted to curb, urging him to focus on Bach, Mozart and Muzio Clementi.

After his father’s early death, Moscheles settled in 1808 in Vienna. His abilities were such that he was able to study in the city under Albrechtsberger for counterpoint and theory and Salieri for composition. At this time he changed his first name from 'Isaac' to 'Ignaz'. He was one of the leading virtuosi resident in Vienna during the 1814-1815 Congress of Vienna and it was at this time that he wrote his enormously popular virtuosic Alexander Variations, Op. 32, for piano and orchestra, which he later played throughout Europe. Here too he became a close friend of Meyerbeer (at that time still a piano virtuoso, not yet a composer) and their extemporized piano-duets were highly acclaimed. Moscheles was also familiar with Hummel and Kalkbrenner. Among the virtuosi of the 1820s, Hummel, Kalkbrenner, Cramer, Herz and Weber were his most famous rivals.
