Dictionaries of violin makers list as many as nineteen makers by this name. Most of them worked in Klingenthal, Saxony, Germany and some are still carrying on there the production of inexpensive trade violins.
The earliest mentioned is Johann Christoph, who worked from 1760 to 1786 and whose instruments are scarce.
Johann Traugott (1819-95) is said to be the most celebrated bearer of the name. His instruments are in the commercial category but the workmanship is good and the tone is pleasing. He worked in the "Hopf style."
His son Franz Johann established himself in Leipzig, where he worked until his 80th birthday in 1927. Respected among violinists, he copied instruments of the Cremona school, adding some Germanic characteristics of his own. He used well-aged wood and produced instruments with a fine, powerful tone worthy of first-class orchestras. He specialized in violas, influenced by those of Maggini.

Friedrick August Glass, I, was working at Klingenthal in 1790, and Friedrick August Glass, II, worked there from 1830-60. The workmanship of both is quite good and somewhat above the "commercial" class. The latter followed a Stradivarius model, slightly modified in the Tyrolese manner. He also produced some violins influenced by Jacob Stainer models.
