Ulrich Wüörner worked in Schwyz as a glass painter from 1604 to 1611. Carl Styger surveyed the records for glass painters in the canton of Schwyz, discovering a small number of panels for which Uli Wüörner was responsible. He was associated with Hans Wüörner whose documented work dates from 1593 through 1619 (Styger, 1885, pp. 8–10; Boesch, 1955, p. 37). A panel in the Los Angeles County Museum is the only known work to bear Uli Wüörner’s signature (US_31).
