Friedrich August von Quenstedt
QUENSTEDT, Friedrich August von.

QUENSTEDT, Friedrich August von.
(1809 - 1889)

(Born: Eisleben, Germany, 9 July 1809; Died: Tübingen, Germany, 21 December 1889) German paleontologist, mineralogist & crystallographer.

In 1830, Quenstedt was appointed assistant mineralogist at the Museum at the University of Berlin. There he undertook the organization of Baron Ernst Friedrich Schlotheim's [1765-1832] recently acquired collection of fossils and minerals. In 1837, he became extraordinary professor of mineralogy and in 1842 ordinary professor of mineralogy and geology at the University of Tübingen, Germany. He remained there until his death.

Rare. A crystallographic textbook that describes the Quenstedt's new method to be used in the science. It is a fanciful method that represents a crystal by projecting on one face of the crystal all the other faces. This curious invention never gained favor and is now a curiosity of crystallographical science. The first part describes the theory of zones and derivation of the projections. The second applies the theory to numerous examples.

Very scarce. A comprehensive mineralogical textbook. It begins with a short history of mineralogy, which is followed in the introductory portion by discussions of goniometers, crystallographic notation and methods of projection, descriptions of the crystal systems, Haüy's and Levy's crystallography, optics, polarized light, optical properties, and pseudomorphs. The descriptive porition of the text reviews the reasons for systematic mineralogy and then persents the descriptive mineralogy. A reference list concludes the work.

Rare. This advanced text on practical and theoretical crystallographical is unusual in that it contains at its beginning a long, detailed historical introduction to the science. This history begins with Theophrastus and works down to Miller providing the derivations of various crystallographic data to the middle of the nineteenth century. Quenstedt then describes the development of the crystallographic systems, followed by discussions of crystallographic zoning and projections. A final section at the end provides a complete overview of twinning. Through out the text, each concept is fully developed through the use of numerous crystal drawings, diagrams, and tables, as well as advanced mathematical derivations.

Contents: Geschichtliche Einleitung (pp. 1-74). Entwickelung der Systeme (pp. 75-128). Deductionslehre (pp. 129-185). Zonenlehre. Projection des Feldspathes auf die Geradendfläche (pp. 186-205). Winkelrechnung (pp. 206-358). Anwendung der Kantenzonenschnitte (pp. 359-409). Zwilling und Hemiedrie (pp. 410-443).
