Edith Can

from Wikipedia, the free encyclopedia

Edith Kann (born April 19, 1907 in Krems an der Donau , Austria-Hungary , † October 7, 1987 in Vienna ) was an Austrian teacher and botanist (algologist). Your botanical author abbreviation is " Can ".

Lunzer See from the Antenscherm. When Kann was working on her dissertation here, only the house on the left was standing.

Life

Her father was a construction engineer and at that time the manager of the construction lot for the Wachau Railway in Willendorf when the famous Venus von Willendorf was found there on August 7, 1908 . Kann therefore lived first in Spitz and from 1911 in Vienna. 1918–1926 she attended the Realgymnasium for civil servants' daughters in Vienna VIII, after which she did the “teaching post” for natural history and geography. 1930 and 1931 she participated in Limnology summer courses at the Biological Station Lunz part and started under Franz Ruttner her dissertation on the ecology of the littoral nursery algae of the Lunzer lake. On March 21, 1931, the doctorate sub auspiciis praesidentis took place and on June 6, 1932, the teaching qualification examination. Since she became unemployed after the probationary year as a result of the global economic crisis, Kann went to Ankara as a private teacher from 1935 to 1936. When she returned to Vienna in 1937/38, she again took a life economics course at the university, but the final exam was abruptly interrupted by the “ Anschluss ”. For 1938–1940 she received a grant from the Kaiser Wilhelm Society to work on the ecology of littoral algae at the Hydrobiological Institute in Plön under Prof. August Thienemann . From 1940 to 1967 she taught at several secondary schools in Vienna (most recently for many years at the Realgymnasium in Rahlgasse). In 1943 her fiancé, the Plön hydrobotanist Hartmut Roll (* 1914), had died.

The Great Plöner See , the subject of investigation May 1938-40.

Botanical research

After the war she continued her algae studies in Lunz during the summer months, using material from lakes at home and abroad - partly with the aim of being able to make statements about the water quality in the trophy system. In the school year 1962/63 she was on leave for this purpose. Her main interest was more and more the blue-green algae (Cyanophyta) from lakes and rivers , for which she also became a specialist in systematic questions, with whom she corresponded worldwide. In 1959 she founded the International Association for Cyanophyte Research (IAC) with the Zurich limnologist Otto Jaag, with symposia for cyanophyte research held periodically. A symposium took place in 2010 in Budweis . She was also often involved with lectures at SIL conferences and also always at the Lunzer Limnological Summer Courses.

Two star operations in 1979 and 1980 could not yet limit her enjoyment of microscopy . It was not until March 21, 1987 that she declared her academic career to be over. On August 4th she suffered a stroke in Lunz , but was found far too late. The eloquent woman was now deprived of her language, partially paralyzed. She died in Vienna on October 7th.

She has published 36 publications on botany and was considered a leading authority on blue-green algae. Your book on the systematics of algae in Austria represented a "valuable enrichment" in the knowledge of this subject.

  • The Lago Maggiore examined Prof. Can 1959-60.- You always showed great skill in recruiting the necessary assistants of their "one-woman expedition" (without a car).

  • The Attersee was explored for its algae flora in 1974-77, with special consideration of the "red and white deep biocenosis " (Geitler 1928; twilight algae at a depth of 15-25 m).

  • Kann examined the algae biocenosis of the Swedish Erken in 1974 and 1977; Posthumously published in 1993.

  • The Salzburger Zeller See , algologically examined 1978-81.

  • The Traunsee was also examined several times in order to determine any effects of calcium chloride discharges on the benthic algae - most recently in 1982.

  • Gomphosphaeria sp., A blue-green alga that, according to Kann, also occurs in Lake Lunz, but could hardly be determined (due to the lack of characteristics).

  • Reichramingbach : Algae vegetation coloration (following Lothar Geitler 1927), examined in 1983 for a report by Upper Austria. Landesregierung.- Kann had several Alpine streams on their "program" - but also the Danube.

  • At the large pond (Svět) of Třeboň (here in the background) is the Hydrobotanical Institute of the Charles University in Prague, where Dr. Can work with Prof. Jiři Komárek on an identification book for cyanophytes.
