Founded by Heinrich Worringen in 1889, his business was listed at Bollwerk 9 in 1895. He is believed to have moved to Altermarkt 47 around 1907. Studenten Vater. (Gustav Vater) also occupied Altermarkt 47, around 1907 - 1911 and probably later. Vater might even have been the supplier of Worringen's porcelain decoration service.
At some point, the spelling of Altermarkt was changed to Alter Markt.
The German spelling for Cologne, varied over the years. So in 1900 the Prussian Minister for Interior Affairs, issued an edict that the correct spelling for Cologne was Cöln. However, on the 1st February 1919, the mayor of Cologne, Konrad Adenauer, stated the official name was again Köln. Probably most people continued to use the spelling they preferred.
By 1922 Heinrich had died and the company was trading as Heinr. Worringen (Witwe). The year 1927 was the last recorded entry as a porcelain decorator, however the shop with the remaining products is thought to have continued to at least 1939.
Purchased stein bodies from: Merkelbach & Wick.
