Theodor Marsson
Friedrich Theodor Marsson (born November 8, 1816 in Wolgast , † February 5, 1892 in Berlin ) was a Prussian , German pharmacist and botanist . Its official botanical author's abbreviation is " T.Marsson ".
Live and act
Theodor Marsson was the son of Aristide Marsson, the city pharmacist in Volga. After completing school in Wolgast, he attended high school in Stralsund . He then learned the pharmacist trade in Wolgast, Stralsund and Blankenburg. He studied chemistry with Justus von Liebig in Giessen and graduated from the University of Berlin in 1841 in pharmacy. In 1844 he took over the Wolgast city pharmacy.
Already during his student days he provided important material for the "Flora von Pommern und Rügen" published in 1840 by Wilhelm Ludwig Ewald Schmidt. From then on, he carried out botanical research alongside his job. In 1856 he was awarded an honorary doctorate from the Ernst Moritz Arndt University of Greifswald . He gained importance as a regional natural scientist with the publication of "Flora of New Western Pomerania and the Islands of Rügen and Usedom" (1869).
In 1870 he sold his pharmacy and moved first to Greifswald and later to Berlin. He turned to microscopic studies. His palaeontological work was of great importance. His work on foraminifera (1878), ostracods and cirripedas (1880) was recognized. His contribution "The bryozoa of the white writing chalk of the island of Rügen" (1887) is to this day the latest monograph of this group of animals for the Rügen chalk , which treats both large groups of bryozoa , Cheilostomata and Cyclostomata , together. The essay "Revision of the bryozoa published by F. von Hagenow 1839-1850 from the chalk of Rügen" (1959) by Ehrhard Voigt should not be regarded as a monograph according to the author. His last work, which dealt with the diatoms , could no longer be completed.
His herbarium went to the University of Greifswald, where it still makes up a significant part of the herbarium collection and where evidence of his scientific work can be viewed in the Institute for Botany and Landscape Ecology.
His daughter Clara Helene married the German physiologist Leonard Landois .
