biography

The son of the Dresden magazine inspector and rent agent Johann Karl Braunsdorf and his wife Johanne Christiane Sophie, née Fischer, first attended the community school in Dresden Neustadt. He received his further training at the Wieland Institute in Dresden and at the Hempel Institute in Leipzig. After graduating from high school at the Nikolaischule , Braunsdorf was enrolled at the Bergakademie Freiberg in 1825 , where he devoted himself to mechanical engineering during his five-year studies. Like his younger brother Bernhard Braunsdorf , he became a member of Corps Montania Freiberg in 1829 .

In 1835 Braunsdorf got a job as a mechanical engineer at the Freiberg Mining Authority. In the same year he obtained iron wire ropes developed by Julius Albert from Clausthal in order to carry out comparative experiments with hemp and iron wire ropes as driving ropes on the horse peg of the Alt-Hörnig-Schacht in Brand . After the Albert ropes had proven advantageous, Braunsdorf had a wire rope machine built in the Freiberg Seilerbahn in 1841 by foreman Johann Traugott Bertram. Since 1840 Braunsdorf was assessor for mechanical engineering with responsibility for the whole of Saxony, in addition he advised the administrations of the Fiskalischen Steinkohlenwerk Zauckerode and the Porzellanmanufaktur Meißen in machine matters. Braunsdorf had been married to Louise Haupt, a daughter of Vice-Mountain Master Friedrich Traugott Michael Haupt, since 1841. In 1846 he was appointed master art director and in 1853 head art master.

Braunsdorf constructed a large number of water column machines, steam machines, Erzwäschen and stamping mills for the Saxon mining industry. In addition, he was a member of the Saxon Engineers and Architects Association and chairman of the administrative committee of the Erzgebirgischer Steinkohlen-Actien-Verein. In 1852 Braunsdorf was the first to be honored with the Albrechtsorder First Class , which was actually reserved for the military, for his services .

His wife died in 1860. Four years later he married Antonie Neumann. In 1869 he was appointed a mountain ridge . In 1880 he left the service. Braunsdorf was the older brother of the Bergamt director Bernhard Konstantin Ludwig Braunsdorf .

On the occasion of the XLIV. The Bergakademie Freiberg honored Karl Julius Braunsdorf in 1993 with the issue of a commemorative medal made of brown Böttger stoneware by the Meissen Porcelain Manufactory, the obverse of which bears Braunsdorf's bust.
