Georg Friedrich von Jäger

Georg Friedrich Jäger , from 1850 by Jäger , (also Jaeger ; * December 25, 1785 in Stuttgart ; † September 10, 1866 ibid) was a German doctor and paleontologist .

Life

Jäger was the son of the medical professor Christian Friedrich von Jäger , who also conducted scientific studies. Georg Friedrich Jäger studied medicine at the University of Tübingen and received his doctorate there in 1808 with a thesis " On the effect of white arsenic in various organisms ". After a study trip in 1809 to Göttingen , through France and Switzerland , where he also visited Cuvier , who was already in contact with his father, in Paris and conducted studies there, he was a doctor in his home town of Stuttgart, from 1841 as senior medical advisor. In 1822 he became professor of chemistry and natural sciences at the upper grammar school in Stuttgart. In addition, he was director ( overseer ) of the Royal Natural History Cabinet from 1817 to 1856, a position previously held by his brother and father. In 1846 he resigned from his post as a high school professor due to increasing hearing loss and in the following years he also increasingly restricted his successful medical practice and in 1856 gave up his position as director in the natural history cabinet.

In 1824 he described the first finding of the ichthyosaur , which the Göppingen doctor Albert Mohr (1709–1789) had made in 1749 in Bad Boll . In 1827 he published a description of the well-preserved plant fossils from the reed sandstone near Stuttgart. Other work concerned deformities of plants (the work earned him recognition from Johann Wolfgang von Goethe ), fossil mammals and turtles.

He was a member of numerous scientific societies, including the Leopoldina (since 1824), the Academie Royale de Medicine in Paris and the Bavarian Academy of Sciences , and he corresponded with numerous European scientists.

His older brother Karl Christoph Friedrich Jäger was also a natural scientist and doctor (senior medical officer). Georg Friedrich von Jäger was the brother-in-law of Gustav Schwab , with whose sister Charlotte (1794-1874) he was married in 1819 in second marriage. He had been friends with the poets Justinus Kerner and Ludwig Uhland since his student days . Jäger's grandfather Georg Friedrich Jäger (1714–1787) was a great uncle by marriage of Friedrich Hölderlin and his doctor in Nürtingen and monastery doctor in Denkendorf (Württemberg) , Jäger's father was a step-cousin of Hölderlin's mother, Johanna Christiana Gok widowed Hölderlin, née. Heyn, himself a second-degree step-cousin of the poet. The Tübingen Stiftsephorus and philosophy professor Gottlieb Friedrich Jäger was his brother.
