How Old is my Leipziger Pianofortefabrik Piano?

¬† ¬†Ronisch prospered between the wars, but the company’s Dresden factory was destroyed in bombing raids in 1945, and production was moved to Hupfeld’s Leipzig factory. The following year Leipzig Pianofortefabrik was born, and by 1986 annual output stood at 8,600. Following German Reunification in 1990, the production process was reorganized and the range redesigned. Carl A. Pfeiffer bought Ronisch in 1997, and established Pianofortefabrik Leipzig GmbH, a new home where the creativity and quality of the Ronisch name lives on.
