LEHMANN, Johann Gottlob.

(1719 – 1767)

(Born: Johannismühle near Baruth, Germany, 11 May 1719; Died: Dresden, Germany, 22 January 1767) German geologist & mineralogist.

Lehmann made many notable contributions to geology, metallurgy, chemistry, and mineralogy. He is considered the founder of stratigraphy. He also founded the Freiberg Bergakademie which became famous under the directorship of A.G. Werner.

Contents: [1-2], Title page, verso blank.; [3]-36, Text.

Very rare. Lehmann's Abhandlung von Phosphoris provides a short account of a broad variety of luminescences. It is one of his earliest publications and professes to give the preparation and uses of phosphors as well as remarks on fire and light and his theory of the origin of the luminescence. Lehmann divides the subject into natural and artificial luminescence, with the latter being prepared either by chemistry or mechanical manipulation, which Lehmann realized was electrical in nature. However, Harvey does not think his treatment was very good.

8°: [16], 268, [8] p., engraved title vignette, 2 folding plates.

Rare. An important work on the origin of metals by the famous German geologist. Lehmann recognized that whatever might be the genetic processes which resulted in the appearance of metals and metallic ores, there were certain situations or places which were more favorable to their development than others. These he referred to as the "matrices" of the metals, stating that metals do neither originate in the air, as believed by many of the older writers, nor in animals or plants, but in the earth's crust, in rocks, or in fossiliferous and other stones.

8°: [80], 240, [8] p., 9 plates.

Very scarce. This good little work, whose forward contains a useful examination of the mineral wealth of the royal prussian provinces titled: Geographiæ subterraneæ, can benefit beginners as well as experienced amateurs of nature and mining. The author does not bury the reader in the pervailing theories, rather he stresses physical examination and practical experience as the best method to obtain knowledge.

Kurzer Entwurf einer Mineralogie

5. German, 1758 [First edition].
Johann Gottlob Lehmann's ... Kurzer Entwurf einer Mineralogie zum Gebrauche für Vorlesungen. Berlin, 1758.

8°: 152 p.

Extremely rare. No copy has been traced. Although the author directed this work to the use of the beginner, it includes many noteworthy ideas, which are the author's opinions rather than a reflexion of the state of mineralogical science. The divisions of the minerals are arranged not according to specific chemical tests, but rather after general principals reported elsewhere on the behavior of the various bodies in fire, water, etc.

Rare. Translated by P.H.T. baron d'Holbach from a number of Lehmann's published works. Each volume has a half-title Traités de Physique, d'Histoire Naturelle, De Mineralogie et de Métallurgie that accurately describes the variety of contents of this work. Volume one begins by describing mines, mountains and rivers in general. This is followed by a discussion of mineralogy (pp. 35-226) with emphasis on economic metals. A treatise on "moufettes" and on the formation of mines follows. This is followed by translations of seven treatises on natural history that speculate on the interior structure of the earth, volcanoes, mineral waters, natural history around Halberstadt, types of marbles, and copper minerals. Volume two provides information on the formation of metals, on mines and their construction, while volume three is orientated on geology, with discussions of the earth in general, and Lehmann's commentary on the theories of Woodward, Whiston, Burnet, Moro, etc., on mountains, and the relationship of metals and minerals to the mountains, and the causes of earthquakes.
