Theodor Herzog

Theodor Carl (Karl) Julius Herzog (7 July 1880, Freiburg im Breisgau – 6 May 1961, Jena) was a German bryologist and phytogeographer.

Biography He studied sciences in Freiburg and Zurich, obtaining his doctorate in 1903 from the Ludwig-Maximilians-Universität München as a student of botanist Ludwig Radlkofer (1829-1927). Later on, he obtained his habilitation at the Federal Polytechnic School in Zurich under the sponsorship of Carl Joseph Schröter (1855-1939).

From 1904 to 1912, he was engaged in a series of botanical excursions; Sardinia (1904 and 1906), Ceylon (1905 and 1908) and Bolivia (1907–08 and 1910–12). In 1920 he became an associate professor of botany at the Ludwig-Maximilians-Universität München, and later succeeded Wilhelm Detmer (1850-1930) at the University of Jena (1925), two examples being: Frullania herzogiana and Luteolejeunea herzogii.

Also named in his honour; Herzogiella (1925), which is a genus of mosses belonging to the family Hypnaceae. Then Herzogianthaceae, which is a family of liverworts belonging to the order Ptilidiales, that family consists of only one genus: Herzogianthus R.M.Schust.(1960). Later published were, Herzogiaria (1981), and Herzogobryum (1963), which are both genera of liverworts.
