Leonhard Sohncke (22 February 1842 in Halle (Kingdom of Prussia) – 1 November 1897 in Munich (German Empire) was a German mathematician, physicist, and mineralogist.

Life and Work[edit]

Leonhard Sohncke was born as son of Ludwig Adolf Sohncke, a professor for mathematics in Halle. Leonhard Sohncke studied mathematics and sciences at the University in his native town, and passed the examination for high school teachers in 1862. With this qualification he became teacher at the reknowned Collegium Fridericianum in Königsberg in the Prussian province of East Prussia, and worked in this position until 1871. Additionally he continued his studies at the University of Königsberg since 1865. In 1866 he got the doctor degree from the University of Halle with a mathematical thesis. In Königsberg, Franz Ernst Neumann interested Sohncke for mineralogical problems. He qualified as private lecturer at the university in 1868 with a thesis on the application of mathematics to crystallography in 1869.

Two years later he was claimed as professor of physics to the Polytechnical School in Karlsruhe, which was the first German Technische Hochschule and the preceding institution of today's Karlsruhe Institute of Technology. In 1883, he changed to the University of Jena as first director of the new founded institute of physics, where he started research on meteorology.[1] Finally in 1886, he moved to the Technical University of Munich, where he worked until his death. He classified the 65 space groups with symmetry operations of the first order, called Sohncke groups, in which chiral crystal structures form.
