J.S. Bach was born in Eisenach, Germany, in 1685 and died in 1750. He came from a long family history of professional musicians including church organists and composers. Like his father, Johann Ambrosius Bach, J.S. (Johann Sebastian) would learn and surpass him in this art of classical music composing.
Bach's childhood wasn't that great as his father passed away when he was 9 and his mother also died when he was a young boy. Although he spent much time with his musically inclined uncles, he also spent time studying and learning from his older brother, Johann Christoph Bach.
Growing up, Bach learned much about organ building. Back in those days, the church organ was a highly complex instrument with many mechanical and moving parts/pedals and pipes. His early experience with repairing and talking with organ builders & performers would prove valuable as he mastered the musical craft.
