Robert Lauterborn

from Wikipedia, the free encyclopedia

Robert Lauterborn (born October 23, 1869 in Ludwigshafen , † September 11, 1952 in Freiburg im Breisgau ) was a German hydrobiologist, zoologist, botanist and historian of science. Its official botanical author's abbreviation is " Lauterborn ".

Life

The son of a Ludwigshafen publisher attended the Latin school in Ludwigshafen until 1885, then the secondary school in Mannheim. He graduated from high school in 1889.

In 1898 Lauterborn described the " cyclomorphosis " of the rotifer Keratella cochlearis .

From 1889 to 1898 Lauterborn studied zoology and botany at the University of Heidelberg under Otto Bütschli, among others . During this time, he was already engaged in cell biological work on diatoms , primal animals and rotifers, among other things . Among other things, he noticed that the shells and carapaces of the plankton rotifer Keratella cochlearis are designed differently depending on the season. In 1898 Lauterborn coined the term " cyclomorphosis ", which is still valid today .

In 1896 he was charged with a thesis on the dinoflagellates Ceratium hirundinella Dr. phil. nat. PhD. In 1898 he submitted his habilitation thesis, a protozoa study on " Flagellates from the Upper Rhine area " .

In 1903 Lauterborn became an associate professor at Heidelberg University . He gave his inaugural lecture on "The Plankton of the Upper Rhine" . He gave lectures on macroscopic and microscopic freshwater fauna, plankton, hydrology, marine fauna, forest zoology and the history of zoology. In addition to his teaching activities, he worked as a reviewer. Among other things, he had orders from the Reich Health Office , where he was particularly concerned with biological examinations on the Upper Rhine, which during this time was increasingly polluted by industrial companies , which resulted in health and ecological problems.

In addition, his extensive research on the Rhine falls during this time, which he summarized in his study "The Geographical and Biological Structure of the Rhine River" and in the context of which he took more than 300 photographs from the source to the mouth between 1907 and 1914. His most important work was not purely biological, but also included geographical and scientific-historical aspects: “The Rhine. Natural history of a German river ” , the first volume of which is subtitled “ The geological and natural exploration of the Rhine and the Rhineland from antiquity to the present ” , comprises as a monograph the entire natural history of the time about this river. In this work he also names the numerous scientists who have dealt with the Rhine and the Rhineland in natural history for several decades. A detailed description is dedicated to the botanist Karl Friedrich Schimper .

Lauterborn's investigations into the occurrence of certain "wastewater organisms" were a decisive basis for the development of the " saprobic system " by Richard Kolkwitz and Maximilian Marsson around 1900, which is still the standard method (DIN 38410) for investigating the water quality of flowing waters. Much of his work focused on nature and environmental protection , for which he actively campaigned.

In 1918 Lauterborn got a job at the Forest Zoological Institute at the University of Karlsruhe , this institute was incorporated into the University of Freiburg in 1920 . From then until his retirement in 1935, Lauterborn was a professor in Freiburg.
