Carl Friedrich Warnstorf

Carl Friedrich Warnstorf (2 December 1837 in Sommerfeld – 28 February 1921 in Berlin-Friedenau) was a German educator and bryologist specializing in Sphagnum studies.

He received his education at the teaching seminar in Neuzelle (1855-1858), afterwards worked as a school teacher in Arnswalde (1859 to 1867), and Neuruppin (1867 to 1899). During this time he published three bryophyte exsiccatae and from 1896 to 1910 with Max Fleischer the forth series named Bryotheca Europaea Meridionalis. Following retirement from teaching he settled in Berlin. In 1917, he was awarded with the title of professor. During World War II his herbarium of 30,000 items was destroyed in the midst of the bombing of Berlin (1943).

The genus Warnstorfia was named in his honor by bryologist Leopold Loeske (1865-1935).
