As business grew, the Zimmermann company expanded to a second factory in 1904. By 1912 over 10,000 pianos were being built a year making it one of the Europe’s largest piano manufacturer. Later, it became a global piano exporter within over 400,000 instruments sold world-wide.
In 1992, C. Bechstein took over the company and incorporated it in its Product Range. Modern Zimmerman pianos are produced in Saxony like all Bechstein Instruments, where the Bechstein company has regrouped its production facilities.
