Johann Christian Zimmermann (Bergrat)
Johann Christian Zimmermann (born April 25, 1786 in Marburg ; † September 29, 1853 in Clausthal ) was German Oberbergrat and from 1811 to 1851 managing director of the Clausthal Mountain School and from 1850 to 1853 deputy miner at the Clausthal Mining and Forestry Office.
Life
Zimmermann, son of the Marburg wine merchant Christian Zimmermann, began his studies at the Philipps University of Marburg as an "architect" in 1802 and stayed there until 1804. He then traveled to Freiberg , which was considered the center of mining in the Ore Mountains, and addressed his wish there Oberbergamt , to be allowed to drive in mines in addition to attending the lectures. This request was almost completely fulfilled.
In May 1807 Zimmermann received his doctorate from the Ruprecht-Karls-Universität Heidelberg and worked from then on as a private lecturer. He got to know Friedrich Creuzer , who had been married to Sophie Leske (1758–1832), widow of the unhappy Nathanael Gottfried Leske , since 1799 . Leske had two children. Zimmermann met his daughter Wilhelmine Eleonore Leske and applied for a marriage permit in the same year.
In 1808 Zimmermann applied for an unpaid extraordinate in Heidelberg, which was rejected. So he turned back to the University of Marburg in 1809 and completed his habilitation at the philosophical faculty for mathematics, physics and architecture. In the same year he moved to Clausthal with his wife and son Gustav, who was also born in 1809, and joined the mining administration of the Kingdom of Westphalia .
Zimmermann was given the post of vice mountain clerk and took on the duties of ironworks registrar and auditing of the ironworks in the Hanoverian Harz Mountains and on Solling . In 1818 he was given the rank of mountain clerk.
At the same time and part-time, Zimmermann worked as managing director of the Clausthal mountain school, which was reclassified in 1811 . He taught mountain studies and mathematics for accounting eleven.
In April 1827 Zimmermann was appointed "Bergsecretär", in September 1839 he received the patent for his appointment as a mountain ridge . In 1844 he made a decisive contribution to the maintenance of the Clausthal mountain school, which had got into a personnel and financial crisis.
In November 1846, Zimmermann was released from his teaching duties and transferred to Friedrich Adolph Roemer and Hermann Koch . Zimmermann was needed to plan a new, lower-lying tunnel to dissolve water in the Upper Harz mining industry ; Koch was put at his side for this.
From 1848, Markscheider Eduard Borchers received the order to carry out the surveying work for the excavation of the so-called Ernst-August-Adit . Borchers had previously received a recommendation from Zimmermann to train as a surveyor at the mining office due to very good performance at the mountain school.
In 1851 the Clausthal Mining Authority presented Zimmermann's plan to the finance minister of the Kingdom of Hanover , which was approved for implementation.
Zimmermann was last retired on February 8, 1853 in the rank of Oberbergrates. Koch, who was carpenter's assistant up to now, took over the management of the tunnel construction and was promoted to the mountain ridge. On September 29, 1853, Zimmermann died as a widower at the age of 67. He left three sons (Gustav, 1809–1875; Friedrich, died 1881; Carl, 1813–1855) and a daughter (Auguste, 1812–1869).
Works
Zimmermann published, among other things, representations from mineralogy, mathematics, physics and mining science (1808), the first part of which builds on the teachings of Abraham Gottlob Werner , whose lectures Zimmermann had attended extensively. The second part describes mining in the Ore Mountains.
In the realignment of discarded veins, beds and seams (1828), he attempted to clarify mathematically how continuations of veins could be found in tectonic vein faults.
The two-volume Harz monograph, dedicated to Franz von Meding , The Harz Mountains (1834) describes the state of the Harz in great detail.
