Augustin Gottfried Ludwig Lentin
Augustin Gottfried Ludwig Lentin (January 4, 1764 – January 18, 1823) was a German chemist. He was a lecturer at the University of Göttingen and subsequently inspector of saltworks, and a writer and translator of works on chemistry and metallurgy. Early life and education. Lentin was born in Dannenberg, Lower Saxony, Germany on 4 January 1764, the son of Lebrecht Friedrich Benjamin Lentin (1736–1804), physician and . He took the degree of Ph.D. at Georg-August-Universität Göttingen and acted as private lecturer in the same university from 1795 to 1801 where he gave courses on technical chemistry  and 'practical economic chemistry'. During this period he translated from English a number of recent publications on chemistry including works by Elizabeth Fulhame, Richard Kirwan and James Keir, and published several books and papers himself on chemical and mining matters. Metallurgy. During this period he visited Wales where he took a particular interest in the copper industry. He spent some time at Parys Mountain on Anglesey, a major source of copper ore during the second half of the 18th century, and also at the works at Ravenhead and Stanley, both near St Helens, Merseyside, where ore from Parys Mountain was  smelted. His findings were described in a publication that appeared in 1800 under the title "Briefe über die Insel Anglesea : vorzüglich über das dasige Kupfer-Bergwerk und die dazu gehörigen Schmelzwerke und Fabriken" (Leipzig : Crusius, 1800). His style has been described as 'cumbersome and pedantic' but his work still represents a useful source for the historians of technology and in particular of the mining and smelting of copper. An English translation appeared in 2007. The frequent papers and translations of the 1790s ceased after 1801 following Lentin's appointment as clerk at a saltworks in Rothenfelde, and subsequently in 1817  as salt inspector at Sülbeck and in the kingdom of Hanover. He also made experiments on the roasting and smelting of ores at Rammelsberg in a large furnace. Death. He died at Sülbeck, near Eimbeck, on 18 January 1823.
