(bapt. Königsberg, Prussia [now Kaliningrad, Russia], 27 Sept. 1630; d Leubus, Silesia [now Lubiąż, Poland], 26 Aug. 1706). German painter. He studied in Amsterdam (under Jacob Backer according to Sandrart) and after working in various places, including Prague and Berlin, in 1660 he settled permanently in Leubus (Lubiąż), the site of one of the largest Baroque abbeys in central Europe, for which he did a good deal of work. He also worked for churches elsewhere and was a fine portraitist. His style was highly emotional, with bold brushwork and flickering light effects. Together with Schönfeld, he was the outstanding German painter of the late 17th century.
