A RARE 1½IN. BRASS REFRACTING LIBRARY TELESCOPE WITH STEINBERG-TYPE BALEEN BINDING

Little is known about the German emigré, Georg Steinberg, who seems to have developed the process of wrapping sticks and telescopes in stained baleen. Although some were stamped Steinberg Patent, no patent was lodged in his name, and it seems likely it was done to deter imitators. Although he basically acted as a subcontractor to instrument makers, several examples of his work have been seen on much older early 18th Century instruments. It seems the process was used between approximately 1815-1840.
