1736-1813 Swiss painter, active in Germany. He was a pupil of Johann Ulrich Schellenburg (1709-95) in Winterthur and continued his training with Johann Jakob Haid in Augsburg between 1756 and 1765. He worked for the court painter Leonhard Schneider (1716-62) in Ansbach from 1757 to 1759, producing large numbers of copies of a portrait of Frederick the Great (probably by Antoine Pesne). This was an important step in furthering his career, as were the months he spent in Regensburg (1764-5) painting miniatures of clerics and town councillors. He was court painter to the Elector Frederick-Christian of Saxe-Weimar in Dresden from 1766 and taught at the Hochschule der Bildende K?nste there. In 1771 he travelled to Berlin, where he painted portraits of Jakob Mendelssohn, Gotthold Ephraim Lessing and J. G. Sulzer. Sulzer introduced him at court, which resulted in many commissions. He was invited several times to teach at the Akademie der K?nste in Berlin, but he remained in Dresden. He often travelled to Leipzig, and in summer he frequently went to Teplitz (now Teplice, Czech Republic) and Karlsbad
