Hugo Thuemler was born in Germany in 1847. By 1894, he was living in Rochester, near Pittsburgh, Pennsylvania. In 1898 he was recorded as running a novelty, china & glass decoration company in Rochester. By 1901 he had relocated his studio to Sewickley, again near Pittsburgh, together with a sales outlet at 1507 Liberty Avenue, Pittsburgh. The majority of his business was supply of custom transfer decorated brewery steins and mugs to the breweries who used them liberally for publicity purposes. He did however supply other items, such as root beer mugs, whiskey jugs and many commemorative pieces, again all transfer decorated. Some of these were purchased from Knowles Taylor & Knowles (KT&K) of East Liverpool. He supplied O'Hara Dial with steins, decorated to order and fitted with special Manning Bowman Co. lids requiring inserts . Thuemler lived at a local hotel, "The Elmhust Inn" which is rumoured to have killed him with their cooking. He died in 1908, The company appears to have been omitted from the Pittsburg directories after this time. However steins were issued until at least 1913.

Straight ink stamp of Thuemler on a 10 ounce stein, this time with a good view of the typical annular rings around the base. 
Thuemler steins only occasionally came with an identifier mark and never with a conventional capacity mark, but are sometimes marked "8", "10", "12" or "16". These are considered to be capacity measures in U.S. Fluid Ounces, So therefore: 8 U.S. Fluid Ounces = 0.237 litres 10 U.S. Fluid Ounces = 0.296 litres 12 U.S. Fluid Ounces = 0.355 litres 16 U.S. Fluid Ounces = 0.474 litres .
