Johann Ambrosius Bach
From Wikipedia, the free encyclopedia
Johann Ambrosius Bach (February 22/24, 1645 – February 20/24, 1695) was a German musician.
The son of Christoph Bach (1613–1661), Ambrosius was born in Erfurt, Germany as the twin brother of Johann Christoph Bach (1645-1693). Ambrosius was employed as a violinist in Erfurt.
In 1671, he moved his family to Eisenach, Thuringia, where he was employed as a court trumpeter and town musician with duties that included performing chorales twice daily from the tower of the town hall, assisting church musicians on feast days, and providing music for civic and municipal functions.
In 1684, he unsuccessfully petitioned to be released from his duties to accept a position in his native town.
He married his first wife Maria Elisabeth Lämmerhirt on April 1, 1668, and had eleven children by her, four of whom became musicians. His youngest, and his most famous child was Johann Sebastian Bach.
He died in Eisenach in 1695.
