After being driven out of Sudetenland during the war, Adolf and Josef Kühnl joined forces with Emil Hoyer to found Kühnl & Hoyer in 1948.

The municipality of Markt Erlbach offered the shooting club’s gallery as a workshop for brass instruments. Alongside a few tools, the company’s only seed capital was its traditional expertise in the construction of brass instruments. To begin with, business was limited to the production of piston valve trumpets and brass instrument repairs.

Kühnl Hoyer Geschichte

After the currency reforms, the workshop equipment was updated to incorporate new technological advances. At the same time, the company’s product portfolio grew. In light of a steady increase in musical instrument demand, the workshop was expanded to include a series of cutting-edge production rooms in 1952, without losing sight of the traditional art of instrument crafting. Based on the rapid growth of the company, the first proper production plant was constructed in 1957.

In 1962, Emil Hoyer left the company, and business was continued by Adolf and Josef Kühnl. Today, the company is run by the third generation of the family, Dieter Kühnl.

The company’s portfolio now spans a range of brass instruments, such as trumpets, cornets, flugelhorns, trombones, tenor horns and baritones, in addition to signal and hunting instruments. Every single instrument is produced in the plant in Markt Erlbach.

Traditional expertise of brass instrument construction is combined with the consistent inclusion of industrial know-how and the latest computer-aided measuring and tuning methods to guarantee truly unbeatable quality. Along with traditional instrument crafting techniques, such knowledge has been passed on to countless apprentices since 1949.
