geological profile created by Lehmann

Template:FixHTML Johann Gottlieb Lehmann (4 August 1719, Langenhennersdorf, Saxony, – 22 January 1767, Saint Petersburg, Russia) was a German mineralogist and geologist noted for his work and research contributions to the geologic record leading to the development of stratigraphy.

He attended the University of Wittenberg, from which he received an M.D. in 1741, and then established a practice in Dresden. Living in Saxony, he developed an interest in the local mining industry, and published on the chemical composition of ore deposits. In 1750 the Royal Prussian Academy of Sciences commissioned him to study mining practices throughout Prussia.

In 1761 the Russian Imperial Academy of Sciences invited him to St Petersburg, where he became professor of chemistry and director of the imperial museum there. At the Beryozovskoye deposit in the Urals he discovered a lead ore with a reddish-orange mineral (PbCrO4), which he named "Rotbleierz" (red lead ore); today in English its name is crocoite.
