Leonhard Sohncke
Leonhard Sohncke was a German mathematician who classified the 65 space groups in which chiral crystal structures form, called Sohncke groups. He was a professor of physics at the Technische Hochschule Karlsruhe from 1871 to 1883, at Jena from 1883 to 1886, and at the Technical University of Munich from 1886 to 1897.
His father Ludwig Adolph Sohncke was professor of mathematics at the University of Halle. He published several books, including Geschichte der geometrie, hauptsachlich mit bezug auf die neueren methoden in 1839, a translation of Aperçu historique sur l’origine et la dévelopement des méthodes en géométrie by Michael Chasles.
