Stephan von Baehr began his career in violin making in 1988 under Reinhard Bönsch in Germany, in whose workshop he became employed in 1990. In the same year, he began his apprenticeship in sculpture under Jochen Heinzmann, and was employed in 1993 by the Sabatier workshop in Paris to restore old instruments, refining his knowledge of style and expertise.
Since then, Stephan has won numerous prizes:

- 1998 - Best placement in violin making at the Manchester International Competition, jury presided by Charles Beare, London. With this recognition granted by his fellow luthiers, Stephan decides to devote himself exclusively - with the generous support of the workshop Sabatier luthiers (Paris) - from this key moment on to instrument making.
