On this date, March 21, 1685, Johann Sebastian Bach was born. By the age of 10, both his parents had died. At 18 he was appointed organist at a church, followed by positions in royal courts. Once, he was imprisoned because the duke he worked for did not want him seeking employment elsewhere. Widowed with seven children, he remarried and had 13 more. Bach composed hundreds of pieces, sometimes at the rate of one per week, and influenced composers such as Mozart and Beethoven. Bach stated: "The aim ... of all music should be none other than the glory of God and the refreshment of the soul."
