Karl Wilhelm Gottlob Kastner (1783 - 1857) was a Germanchemist and natural scientist.
Kastner is best known today as the teacher of chemist Justus Liebig.
Kastner received his doctorate in 1804 and began lecturing at the University of Jena. He moved on to the University of Heidelberg and became professer at the University of Halle in 1812. In 1818 he relocated to the University of Bonn. Again he moved on, partly for political reasons, to the University of Erlangen, where he remained for the remainder of his professional life. Liebig, who had come to Bonn to study with Kastner, followed him to Erlangen and received his doctorate in 1822.
Als Doktorvater betreute der berühmte Chemiker KarlWilhelmGottlobKastner den jungen Justus von Liebig, und von Liebig begleitete ihn, als Kastner nach Erlangen umzog, wo von Liebig 1822 promovierte.
An der Universität Gießen studierte August Wilhelm von Hofmann, den von Liebig betreute und der 1841 promovierte.
When the chemist, August Wilhelm von Hofmann, received a chair, it was decided to construct an institute for chemistry, which the architect August Dieckhoff built in 1864-67 and in its time was the largest chemistry laboratory in the world.
