Friedrich Lenz (biologist)
Friedrich Matthias Lenz (born September 14, 1889 in Prosterath , † September 7, 1972 in Neuss ) was a German hydrobiologist and limnologist . His scientific life's work is his systematic and ecologically oriented research on chironomids and other insect species, as well as various limnological and fishery biological studies.
Live and act
Born in Prosterath near Trier, Friedrich Lenz spent his youth in Neunkirchen / Saar. There he passed the final examination in 1909. He studied natural sciences and mathematics in Bonn, Freiburg and Münster. In Münster he was so impressed by the lectures given by the private lecturer August Thienemann that he became interested in inland waters and their research.
Seriously wounded in France during World War I and forever hearing impaired, he received his doctorate in July 1919 from the University of Kiel under August Thienemann on the subject of “The Metamorphosis of the Chironomus Group. Morphology of the pupae and larvae ”. Research on the chironomids occupied him all his life.
At the end of the war in 1918, Friedrich Lenz was employed as the first assistant at the hydrobiological institute of the Kaiser Wilhelm Society in Plön . Soon after completing his doctorate, when there was no “university society” in Germany, Lenz began to hold adult-education courses at the old “ Biological Station ” in Plön, the predecessor of the Max Planck Institute for Limnology .
In 1931 he completed his habilitation at the University of Kiel, where he was appointed adjunct professor in 1934.
In addition to his research and teaching activities, Lenz devoted himself to scientifically-organized tasks, including building up the "International Association for Theoretical and Applied Limnology" (IVL, now SIL ), founded in 1922 . He was elected Secretary General at the founding meeting and held this office until 1948. In the same year he was appointed vice-president of the IVL, a little later also a representative of the German section.
In the early 1930s he did research in Karelia for several months .
In 1934/35, together with Harald Sioli, he carried out fishery-biological and limnological studies in northeastern Brazil, so that the limnology of tropical waters in an arid area became known.
Friedrich Lenz's estate is in the archive of the Max Planck Society and previously in the Limnological River Station of the Max Planck Institute in Schlitz .
