# Carl Giesecke

Carl Giesecke (2 September 1812 – 28 September 1888) was a German organ builder who became known as a supplier of reed pipes.

## Life and work

Born in Göttingen, Giesecke was the son of the clothier Otto Heinrich Giesecke and Marie Caroline Aue. His grandfather and great-grandfather were surgeons in Schoningen.
Giesecke learned organ building from 1840 to 1844 from Johann Friedrich Schulze, on whose style he oriented himself structurally and tonally. On 1 April 1844, he acquired citizenship in Göttingen, set up his own business there and was soon one of the most important organ builders in southern Lower Saxony. He initially supplied Schulze with reed stops and other organ parts. By 1860, the workshop had attained a leading position as a subcontractor and from 1870 onwards supplied reeds and organ parts exclusively. Until 1869, he created over 20 new buildings.
On 28 July 1844 he married Wilhelmine Rosine Charlotte Schulz from Hameln, with whom he had six children. His son Hermann (11 May 1847 in Göttingen - 12 February 1928 ibid) was also an organ builder and partner of his father shortly after 1880. According to a contractual agreement, the company traded as "Carl Giesecke & Sohn" from 1884. Hermann took over the construction of the reeds from then on, while his father only made mechanical parts. In view of the growing demand for reeds, the building of complete organs was abandoned.
Since Hermann had no male descendants, the company was leased in 1909 to Adolf Hammer, the co-owner of the Emil Hammer Orgelbau [de] company. Hermann's two daughters Helene Giesecke and Gertrud Steggewentz became partners and the company was named "Gieseckes Erben und W. Furtwängler". The number of employees grew to over 75 after the Second World War. In 2006, the company was transformed into a limited liability company. Continuing the company tradition, about 25 employees supplied organ builders worldwide with reed and labial pipes. In 2012, the company filed for insolvency, as a result of which the workshop was dissolved and business operations ceased.
