LEONHARD, Karl Cäsar von.

(1779 – 1862)

(Born: Rumpenheim near Hanau, Germany, 12 September 1779; Died: Heidelberg, Germany, 23 January 1862) German mineralogist & geologist.

Leonhard was the father of Gustav von Leonhard. He was a professor of mineralogy and geognosy at the University of Heidelberg from 1818 onwards. Earlier, he was land assessor in Hanau. He was the founder and publisher of one of the first mineralogical magazines, Taschenbuch für die gesammte Mineralogie, which is the ancestor of today's Jahrbuch [Neues] für Mineralogie, Geologie, und Palaeontologie. Leonhard built a personal mineral collection of over 8,000 specimens from the Harz, Switzerland, Poland, Vesuvius, Eifel, France, Iceland and elsewhere. This collection was acquired by the University of Göttingen after his death.

Rare. Co-authored with Ernst Karl Friedrich Merz [see note below] and Johann Heinrich Kopp. This volume consists of a systematic survey of various mineralogical properties in the form of a series of tables. The lengthy descriptions give ample reference to external characters and the chemical qualities. In many instances throughout the text of this volume, the authors have also included remarks that reflect the inadequacies of science they had personally experienced; they fully understood the limitation of mineralogical science in their own time and attempt to convey this information to the reader. Leonard wrote the oryctognosy section, Merz the oryctology, and Kopp the chemical sections.

Ernst Karl Friedrich Merz. (Born: Hanau, Germany, 28 February 1776; Died: Bruchköbel, Germany, 19 November 1813) German clergyman & naturalist. Merz was a priest first in Hanau, then at Bruchköbel near Hanau.

Rare. Co-authored with Johann Heinrich Kopp and Carl Ludwig Gaertner [see note below], this remarkable mineralogy was the product of two years cooperation between the authors. It was intentionally written as an introductory volume to Leonhard, Merz and Kopp's earlier, Systematisch-Tabellarische Uebersicht und Charakteristik der Mineralkörper (Frankfurt am Main, 1806) [see previous entry].

After the short introduction which covers general information and definitions, the Propaedeutik is divided into seven major sections. The first of these concerns mineralogy in general, and covers outer characteristics like color, crystal form, cleavage, and taste, inner characteristics like hardness, phosphorecenze, magnetism, and electricity as well as classification schemes and nomenclature. Section two gives a distinctly Wernerian view of geognosie and how the earth is geologically ordered, ore deposits, a theory of the planet's structure, and geological nomenclature. The third section concerns fossils. Section four is a highly interesting account authored by Leonhard on the collecting of minerals. Details include instructions for the numbering and labeling of specimens as well as the importance of cataloging ones collection. Section five briefly lists the epochs thus scene in the history of mineralogy, with Werner [q.v.] being given the most prominent typeface, followed next by Haüy, Agricola, etc. The sixth section is an important and extensive bibliography covering mineralogy, geognosie, and paleontology. Compiled before the availability of other major bibliographic works, this mineralogical bibliography listing 2740 items is a remarkably complete list of books available to the mineralogist of the period. This classified bibliography was prepared by Gaertner, and it is divided into seventeen general categories including literature & history, ancient mineralogy, periodicals, nomenclature, dictionaries, textbooks, systematic, topographical works, chemical, geology, and paleontology. Concluding the work is the seventh section, which gives an alphabetical list of all the authors mentioned in the bibliography together with short biographical notes. In some instances, this is today still the only biographical information availiable about the authors. A very scarce book, probably due to a high cost in production.

Johann Heinrich Kopp. (Born: Hanau, Germany, 17 September 1777; Died: Hanau, Germany, 28 November 1858) German physician & chemist. Kopp held an advanced degree in chemistry and was appointed professor extraordinary in 1843 and professor ordinary in 1853 in physics and chemistry at the University of Giessen.

Karl Ludwig Gaertner. (Born: Hanau, Germany, 7 January 1785; Died: Hanau, Germany, 3 October 1829) German apothecary. Gaertner opened a pharmacy in Hanau and became director of the Wetterau Society for the collecting of natural objects in that city.
