Liebisch's Portrait

Theodor Liebisch (29 April 1852, Breslau – 9 February 1922, Berlin) was a German mineralogist and crystallographer.

Biography

[edit]

In 1874 he received his doctorate from the University of Breslau, then worked as an assistant to Gerhard vom Rath at the University of Bonn. After several years spent as a curator at the mineralogical museum of the University of Berlin, he became an associate professor of mineralogy at Breslau (1880). Afterwards he successively served as a full professor of mineralogy at the universities of Greifswald (1883/84), Königsberg (from 1884), Göttingen (1887–1909) and Berlin (1909–22). He was an editor of the periodical "Jahrbuch für Mineralogie, Geologie und Paläontologie".[1][2]

His name is associated with "Liebisch twinning", a complex type of crystal twinning that is a combination of the Dauphiné and Brazil twinning laws.[3]
