The certificate contains the first documented reference to the company, with Christian August Seydel being registered as the company founder. The factory was established in Klingenthal at the foot of the famous Aschberg (literally ‘Ash Mountain') and became one of the biggest harmonica factories in Saxony. In 1882, C.A. Seydel died, and his son Richard took over. One year later his brother Moritz joined them, and the company name changed to C.A.Seydel Söhne (C.A. Seydel and Sons).
