Georg Hans Emmo Wolfgang Hieronymus (born February 15, 1846 in Schöneiche , Neumarkt district, province of Silesia , † January 18, 1921 in Berlin ) was a German botanist. Its official botanical author abbreviation is " Hieron. "

Life

Hieronymus was the son of the manor owner Carl Hieronymus and his wife Emma Jaeschke. After his father's death in 1854, the family moved to Görlitz, where Hieronymus passed his Abitur at the grammar school in the old Görlitz monastery in 1866. He first studied medicine in Zurich, but turned to botany after a year. He studied in Bern until 1868, in Berlin from 1868 and at the University of Halle from 1870 to 1872. He also intended to do a doctorate (the related work on Centrolepidaceae he had published in 1873), but initially followed a call from Paul Günther Lorentz as his assistant in Argentina in 1873 . He received his doctorate from the University of Santiago de Chile. With Lorentz, he went on an expedition to the Argentine Andes as far as Bolivia. In 1874 he succeeded Lorentz, who had resigned, as professor of botany in Córdoba (Argentina) , which he remained until 1883. He explored the flora in Argentina, Bolivia, Brazil and Uruguay and in particular the mountainous region around Cordoba. He was supported by the merchant and botany lover Gustav Niederlein . He was twice on vacation in Germany, in 1878 to visit his mother and in 1879/80. During the second stay he married Eva Jaeschke. From 1883 he was a private scholar in Breslau (he was free from financial constraints) and from 1892 curator of the Botanical Museum at the Botanical Garden in Berlin, which was under the direction of Adolf Engler . He had to experience how his eldest son died as a military doctor in 1918 during World War I and died in 1921 after a stroke after his wife had died two years earlier.

The collections built up by him and Lorentz were partially evaluated by August Grisebach in Göttingen (Grisebach, Plantae Lorentzianae 1874, Symbolae ad Floram Argentinam 1879). The plant systematic evaluation of Grisebach was unsatisfactory (he was known as a plant geographer), but the herbarium of Hieronymus, which finally came to Berlin, was evaluated there by many other botanists.

In Argentina he published a monograph on Lilaea (aquatic plants that belong to the trident family ) and in 1882 a monograph on the useful plants of Argentina (Plantae diaphoricae florae Argentinae). After returning to Germany, he turned to cryptogams, especially ferns and algae (collecting important herbaria that also came to Berlin) and for 28 years from 1893 published the magazine for cryptogams Hedwigia (from 1905 until shortly before his death as Sole editor). In the case of algae, he also examined their development and biology and unicellular algae using the latest microscopic techniques. He also examined plant galls , examined their distribution and anatomy and built a herbarium for them. In Berlin he devoted himself to ferns in addition to the lower algae and expanded the fern collection of the Botanical Museum. He worked in particular on ferns from tropical Africa and South America as well as moss ferns and was supported at the museum by former Lieutenant Colonel Guido Brause . But he also worked on phanerogams, especially from South America and here from Argentina.

He also contributed to the compilation The Natural Plant Families by Carl Prantl and Adolf Engler .

Honors and memberships

His classes were in honor Hieronymiella Pax from the family of Amaryllidaceae and Hieronymusia Engl. The from the family Saxifragaceae (Saxifragaceae) named. In 1895 he became a member of the Leopoldina .
