Georg Hans Emmo Wolfgang Hieronymus

Georg Hans Emmo Wolfgang Hieronymus (1846–1921) was a European botanist of German extraction. He was born in Silesia and died in Berlin.

He began his career as a medical student in Zürich and Bern from 1868 to 1870, but became interested in botany, instead. He then studied at the University of Halle, where he earned his doctorate in 1872.

Hieronymus was professor of botany in Córdoba, Argentina, from 1874 to 1883. While in South America, he investigated flora native to Argentina, Bolivia, Brazil and Uruguay. He also lived in Breslau, 1883–1892, and Berlin, where he was curator of the botanic garden and botanic garden museum starting in 1892. In the same year he started to edit the exsiccata series Herbarium cecidiologicum together with Ferdinand Albin Pax. He edited the botanical journal Hedwigia for 28 years.

Hieronymus' specialty was in ferns and algae. He was known for his plant collections in both central Europe and in much of South America.
