Dietrich Georg von Kieser
Dietrich Georg von Kieser (24 August 1779 – 11 October 1862) was a German physician born in Harburg. He studied medicine at the Universities of Würzburg and Göttingen, receiving his doctorate from the latter institution in 1804. For most of his career he was a professor at the University of Jena, where from 1824 to 1862 he served as a "full professor". He was an advocate of balneology, and beginning in 1813 was a physician at the therapeutic spas at Heilbad Berka/Ilm. While working as a professor at the University of Jena, Kieser operated a private  ophthalmology clinic from 1831 to 1847, and from 1847 until 1858 he was director of the mental hospital in Jena. With Adam von Eschenmayer and Christian Friedrich Nasse, he published the 12-volume "Archiv für den thierischen Magnetismus" ("Archive for animal magnetism"). Kieser was politically active throughout his career; in October 1817 with philosophers Lorenz Oken and Jakob Friedrich Fries, he partook in the historic Wartburg Festival. In 1858 he was named president of the Deutsche Akademie der Naturforscher Leopoldina. He died in Jena. A magnesium sulfate mineral known as kieserite is named after him.
