Career
He apparently lived his entire life in Berlin and is known to have been an instrument maker there from, at the latest, 1695. He succeeded Christoph Werner in 1707 as official maker to the court. He delivered a harpsichord to the court at Köthen in 1719 on the recommendation of Johann Sebastian Bach, which was probably the instrument for which Bach composed Brandenburg concerto no.5 as a show-piece.
Three of his harpsichords survive: a single-manual, in Hudiksvall, Sweden, is signed "Berlin, 1710".
In Schloss Charlottenburg, Berlin, there is one single-manual, which belonged to Queen Sophie Charlotte, and one double-manual, both unsigned and probably made for the court. Friedrich Mietke (1746 – c 1805) was the son of Georg Mietke, and was taught by him until 1765.
He became maker to the court in 1770.
