her shortly thereafter. They had no children. J. C. Bach performed symphonies and concertos at the Hanover Square Rooms. This was London's premier concert venue in the heart of fashionable Mayfair. The surrounding Georgian homes offered well-to-do clientele for his performances. One of London's primary literary circles, which included Jane Timbury, Robert Gunnell Esq., Lord Beauchamp, and the Duchess of Buccleuch, was acquainted with Bach, and members were regular attendees at his events. In 1777, he won a landmark case, Bach v Longman, which established that (in English law) copyright law applied to musical scores. By the late 1770s, both his popularity and finances were in decline. By the time of Bach's death on New Year's Day 1782, he had become so indebted (in part due to his steward embezzling his money), that Queen Charlotte stepped in to cover the expenses of the estate and provided a life pension for Bach's widow. He was buried in the graveyard of St. Pancras Old Church, London. Legacy A full account of J. C. Bach's career is given in the fourth volume of Charles Burney's History of Music. There are two others named Johann Christian Bach in the Bach family tree, but neither was a composer. In 1764, Bach met with Wolfgang Amadeus Mozart, who was aged eight at the time and had been brought to London by his father. Bach then spent five months teaching Mozart in composition. Bach is widely regarded as having a strong influence on the young Mozart, with scholars such as Téodor de Wyzewa and Georges de Saint-Foix describing him as "The only true teacher of Mozart". Mozart arranged three sonatas from Bach's Op. 5 into keyboard concertos, and in later life Mozart "often acknowledged the artistic debt he owed" to Johann Christian. Upon hearing of Bach's death in 1782, Mozart commented, "What a loss to the musical world!" Works The works of J. C. Bach are given 'W' numbers, from Ernest Warburton's Thematic catalog of his works (New York City: Garland Publishing, 1999). Bach's compositions include eleven operas, as well as chamber music, orchestral music and compositions for keyboard. References Notes Further reading Hans T. David, A. Mendel, C. Wolff.
