He was famous as a musician during his lifetime because he was talented.
Composer.
The Golden variations were written 9 years before JS Bach's death.
Music composed for and played on the organ was extremely popular during the lifetime of J.S. Bach (which I assume is the Bach being referred to). Master Bach had 20 children. 10 died in infancy and 3 went on to become composers/musicians themselves. None quite equalled Papa Bach, but Carl Philipp Emanuel (CPE Bach) didn't fall too far from the tree.
Johann Sebastian Bach was not deaf, Beethoven was. Though Bach was blind for most of his life.
No, John Sebastian Bach was not deaf, that's Beethoven, but I think Bach was blind by the end of his life.

The Art of The Fugue. Bach died during the composition of the last fugue of the set.
He really had too few to mention. As a composer, Bach was known only in his immediate circle, and considered as good as anybody else, better than most. As an organist, he was considered the best in Europe, only Handel being placed in his class - and while Bach wanted to meet Handel, they never did.
