Heinrich Baensch was born 27th August 1830. His factory, manufacturing porcelain tableware, was founded in 1858. Heinrich was known still to be in charge in 1883. Heinrich's son Alfred succeeded his father, but took the business into bankruptcy in 1931, after which time it was owned by Gustav Becker. It was nationalised and merged with V.E.B. Colditz in 1946. The factory ceased production and closed in 1990 at the reunification of Germany. The buildings are now a car dealership.
