Hans-Jürgen Mühle was born on September 22nd, 1941 in Schweidnitz. In his earliest childhood his mother fled with him in the freezing winter via Dresden to Glashütte. Here he completed an apprenticeship as a precision mechanic before he studied precision mechanics and optics in Leipzig and Jena after his time in the army. As a young man, he took over his father’s business “Ingenieur Hans Mühle” in Glashhütte, until it was expropriated in 1972. In the following years, Hans-Jürgen Mühle worked in sales at VEB Glashütter Uhrenbetriebe, later became sales manager and, after the German reunification, commercial director of GUB. In 1994 he re-founded the company of his ancestors: as Mühle-Glashütte GmbH nautical instruments and precision mechanics.
