[1] Johann Bernhard Bach was born in Erfurt in 1676, in the house named "Zu den drei Rosen" (The Three Roses) on Junkersand Street, and was baptized on 25 November 1676 in Erfurt's Kaufmannskirche (Merchant's Church).
In 1703, John William III, Duke of Saxe-Eisenach called him to Eisenach to serve as harpsichordist at the ducal court.
In Eisenach, he also became the organist at St George's Church, succeeding his uncle Johann Christoph Bach.
From 1708 to 1712, Johann Bernhard Bach worked together with Georg Philipp Telemann who held, first, the position of the leader of the violin section, and, from August 1709, that of a conductor (Kapellmeister) at Eisenach's ducal orchestra.
This latter was to succeed his father Johann Bernhard as organist at St George's Church in Eisenach.
