Adolph Keferstein
Heinrich Christoph Adolph Keferstein (born August 4, 1773 in Kröllwitz , † August 12, 1853 in Weida ) was a German inventor, manufacturer and paper miller.
Life
Keferstein came from a long-established family of paper millers. He was introduced to paper production at an early age by his father Georg Christoph Keferstein . In 1802 he took over his father's paper mill , which had been in operation in Weida since 1700, but was under the management of his brother at the time of his father's death in 1802. His great interest was in the development and construction of a cloth shearing and spinning machine and the development of a continuous paper machine, for which he drew a design in 1816 . In 1819 he designed a cylinder mold machine that produced sheets of paper 60 yards long . This paper machine , developed in Weida and mainly made of wood, is considered the first of its kind in German-speaking countries, but it could not be used professionally due to the wood construction. Only after the expiry of a Prussian patent held by an Englishman on this machine type since 1818 , which secured him sole production, in 1833, machines based on Keferstein's design were produced in Germany that were also used in the German paper industry. Keferstein also drew plans for the Weimar waterworks . For the most part, Keferstein was unable to capitalize on any work.
Keferstein had been married to the daughter of the preacher Schwalenberg from Berßel since 1798 . The marriage resulted in four sons, three died in childhood. His nephew Christian Keferstein was a mineralogist and ethnographer .
