Johann Christian Bach, German composer of the Classical Era, was the youngest son of Johann Sebastian Bach by his second wife Anna Magdalena Bach. JC Bach, as he was commonly called, was born in Leipzig in 1735. He studied with his father until aged 15, then in Berlin with his half-brother Carl Philipp Emanuel, considered the best musician in the Bach family that time.
In 1754 he went to Italy, became an organist in Milan Cathedral, and abandoned Protestantism for Roman Catholicism.
Johann Christian Bach went to London in 1762 and was appointed music master to Queen Charlotte Sophia, wife of George III. Since then he has been called the 'English Bach' or 'London Bach.'
In London, he became friends with the boy genius Mozart who was on his first European tour with family. He introduced Mozart to English musical society. Mozart wrote his first three symphonies under the influence of Johann Christian Bach.
JC Bach made London his permanent home. Sadly, his popularity faded in the late 1770s, and his health declined following financial troubles. He was soon forgotten after he died in London, aged 46. He is buried in St Pancras' Churchyard.
His music, with a blend of the Italian fluency and grace, along with well-founded German techniques, appealed to Wolfgang Amadeus Mozart.
Johann Christian Bach, sometimes regarded as hedonistic compared to his half-brother CPE Bach, produced elegant music simply suited to its social purpose.
