(Born: Breslau, Germany, 29 April 1852; Died: Berlin, Germany, 9 February 1922) German petrologist & mineralogist.

Liebisch graduated from the University of Breslau with a petrographical dissertation in 1874. He became assistant to Gerhard vom Rath at Bonn, and afterwards curator of the Mineralogical Museum of the University of Berlin. Later, Liebisch was appointed successively professor of mineralogy and crystallography at Breslau (1880), Greifswald (1883), Königsberg (1884), Göttingen (1887) and Berlin (1908), retiring in 1921. From 1885 to 1921, he was one of the editors of the important Neues Jahrbuch für Mineralogie, Geologie und Paläontologie.
