Paul Günther Lorentz
Paul Günther Lorentz, out as Pablo Lorentz, ( born August 30, 1835 in Kahla, † October 6, 1881 in Concepción del Uruguay), in South America and the Spanish -speaking countries known as Pablo Lorentz, was a German botanist who mainly to the Bryology, ie the collection and study of the mosses, specialized. He achieved notoriety primarily for his botanical collections in South America, where he collected more than 1,000 science as yet unknown species of vascular plants, mosses and lichens. His botanical author abbreviation is " Lorentz ".
Life
Paul Günther Lorentz was born the son of a local politician and pastor 's son Heinrich Moritz Lorentz, who worked as a county judge in Kahla, city mayor in Ronneburg, district magistrate in Kahle and council in Altenburg, and his wife Emma, daughter of the Privy Court Councillor Karl August Schubart. 1880 married Johanna Lorentz French
Lorentz began his study of theology at Jena and heard alongside botany courses at Matthias Jacob Schleiden. The continuation of studies performed in Erlangen and here he continued his botanical studies at Adalbert Schnizlein. As a candidate of science theology he finished his theological studies in 1858 in Altenburg and subsequently focused entirely on the botany. To this end, he acted in the same year to Munich and studied with Carl Wilhelm von Naegeli at the Ludwig- Maximilians- University, where he received his doctorate in 1860 with his doctoral thesis contributions to biology and geography of mosses.
From 1860 to 1869 Lorentz worked in Munich and focused on the biology of mosses. In 1864 he was a lecturer in botany and 1870 he was a professor of botany at the newly established Faculty of Natural Sciences of the University of Cordoba, Argentina. From here he undertook a series of research and collecting trips in the Argentine hinterland. In 1874, he was terminated, together with a number of other scientists from Germany, for political reasons. Later he became a secondary school teacher at the Colegio Nacional in Concepción del Uruguay. Even from here he led until his death from numerous collecting trips. Lorentz died 1881 in Concepción.
Work
During his time in Munich from 1860 to 1869, the research of Lorentz mainly on the history of development, anatomical classification and geographical distribution of the mosses concentrated. Together with Wilhelm Philipp Schimper he founded the geography of mosses to complement the already established plants and geography along with Ludwig Molendo (1833-1902), he led numerous collecting trips, especially in the Alps, by. Due to its anatomical and developmental studies he introduced the detection of a set of morphological criteria such as the leaf and stem cross-section in the systematic research of the Moose.
The main work of Paul Günther Lorentz lay in his numerous botanical collections in which he gathered up new species over 1000 science. He was the first botanist, who carried out extensive and scientifically oriented travel in Argentina. He traveled 1871/72 together with the geologist Alfred Wilhelm Stelzner ( 1840-1895 ) in the mountainous regions of Tucumán and Catamarca to the Laguna Blanca. 1872/74 he traveled through the province of Jujuy, 1879 through the Pampas to the Río Negro and 1881 in the Sierra Ventana to Bahía Blanca. His collections have been processed by different experts such as August Grisebach ( vascular plants ) and Karl Müller- Hall ( mosses); alone in his first two trips, he collected more than 3000 vascular plants, of which 567 science until then were unknown. Among the new species also were 22 and 480 lichens moss species.
He was also the first to describe the vegetation areas of Argentina and anfertigte a phytogeographical map of the country.
Appreciation
Paul Günther Lorentz is the namesake of the Botanical Garden Parque Botanico Andino " Paul Günther Lorentz " in San Fernando del Valle de Catamarca, Catamarca, Argentina.
