How a company acquired the name of a dwarf

PERKEO was the name of the court jester and dwarf serving under the Elector of the Palatinate , Karl III Philipp, in the 18 th century. The little fellow first saw light around 1702 and was baptized with the name Clemens. At sixteen he was appointed court jester by Karl Philipp. The Elector, who enjoyed the pleasures of a good wine, was impressed by the way the young Clemens was able to hold his liquor.

Today there is still a barrel housed in Heidelberg castle, which holds 221,726 liters. When asked by his employer and master the Elector whether he would dare drink the entire contents of the barrel, Clemens, who was just over three feet tall, replied cheekily and brazen-faced: „Perchè no?“ – why not? Clemens often used this expression which became commonly used in the local tongue of the Palatinate . Thereinafter he was called PERKEO. A drinking song written by Josef Viktor von Scheffel described PERKEO with the following words: "...And there was the dwarf PERKEO that housed in Heidelberg’s castle, small and wee in growth was he; his thirst, however, momentous".

This depiction, which was to be an apt description of the young company’s acetylene generator, prompted the company founder, Hermann Stahl, to give the company the name PERKEO, whereupon he adapted the phrase “ … small and wee in growth; but its performance is momentous. This laid the cornerstone for the development of portable and wheeled small-size oxy-gas welding, cutting and brazing equipment and systems.
