Although Stoelzels name is generally connected to this valve system, some think it was a joint effort of the two “craftsmen” Stoelzel and Bluhmel , working together as a team in Berlin in the first quarter of the 19th century.

Stoelzel was a Saxon and Bluhmel was a Schlesien. The exclusive patent rights to this valve system was ultimately given to or purchased by Stoelzel and to this day it bears his name. The interesting question is, why did the valve system not gain popularity in the German speaking principalities where it was invented, but accepted to a larger extent in Great Britain and France where it was applied as seen here on a Cornopean.

This instrument bears a British makers mark “an Irish harp” and was imported into the U.S. by John Howard Foote, probably before the Civil War. Interesting about this horn is the original tarred wooden case to make it waterproof, and the pigtail and straight crooks which pitch the instrument to ” Bb, Ab, FA, LA, and SOL”. There is also a screw in Lyre and a bubble glass painting of the period, of a musician holding this horn. Notice that the “SOL” crook is in the upright position in the painting.

This horn was found in Fond du Lac Wisconsin at an estate sale in early 1970.
