The history of the Rösler company and brand goes back to the second half of the 19th century and begins with the large Rösler family of north Bohemia and Saxony. The year 1878 is considered the official date when the Rösler factory was founded by Gustav Rösler.

Ludwik Gatter bought the company from his sister Helena Rösler in 1900 and successfully presented his instruments to the international markets. Rösler instruments were sold even in Great Britain and South Africa.

The company flourished after the creation of independent Czechoslovakia. Ludwik Rösler died in 1928 but left two able successors, his sons Reiner and Walter. Both were top piano experts and first-class designers as well as efficient businessmen who exported Rösler pianos to 18 European countries.

During the 70 years of existence of the Rösler family factory, the Rösler brand built such a strong position that its reputation survived for another 60 years after the factory closed. After more than 115 years after its creation, the Rösler brand was acquired by PETROF, a leading European piano manufacturer.
