Christoph Friedrich Jasche

Christoph Friedrich Jasche (born October 15, 1780 in Drübeck , † June 12, 1871 in Ilsenburg ) was a German naturalist.

Life

He studied at the Institute for Mining and Metallurgy in Berlin and went on study trips with the support of Count Christian Friedrich zu Stolberg-Wernigerode . To the full satisfaction of the Count, he made a geognostic description of the Lauchhammer ironworks and the Peterswaldau area . As a result, on March 6, 1802, he was appointed Count's Hüttenkommissari (us). On March 1, 1805, he was promoted by Count Stolberg as mining commissioner for the scientific and technical operation of the mining industry, particularly for the administration of the iron stone mines on the Büchenberg near Elbingerode , and moved into an apartment there. There he experienced the time of the Westphalian occupation . In 1819 he was appointed director of the iron and steel works in Ilsenburg , which position he later left.

House built for Jasche in Ilsenburg in 1828 (2010).

Jasche received his doctorate as Dr. phil. and became a member of the Mineralogical Society of St. Petersburg , the Natural Science Association of the Harz Mountains and the Scientific Association of Wernigerode . He was also a corresponding member of the Mineralogical Society in Jena and the Society of Friends of Natural Science in Halle, as well as a member of the Acad. national to Paris .

In 1812, Jasche classified the minerals in the Count's natural history cabinet . When the new office building in which this cabinet was located was sold in 1812, Jasche moved it to the 2nd floor of the right wing of the orphanage in Wernigerode.

He left behind numerous writings in the field of mineralogy and geology as well as the following extensive collections:

• the oryktognostic collection with 3126 pieces
• the geognostic collection with 950 pieces
• the fossil collection , with which u. a. Leopold von Buch occupied several days, comprised 4150 copies
• the Coleoptern collection with 4700 copies
• a collection of 111 stuffed birds.

These collections were inherited by Jasche's son Robert, who was then a smelter in Ilsenburg. He sold it to Count Otto zu Stolberg-Wernigerode in 1871 . At the beginning of the 1930s this collection was sold to the Prussian State Geological Institute in Berlin.
