Edith Kann

Edith Kann (19 April 1907, Krems an der Donau – 7 October 1987, Vienna) was an Austrian teacher and botanist, specializing in phycology.

[4] For 1938–1940 she received a scholarship from the Kaiser Wilhelm Society to study the ecology of littoral algae at the Hydrobiological Institute in Plön under the supervision of August Thienemann.

From 1940 to 1967 she taught at several secondary schools in Vienna (most recently for many years at the Realgymnasium at Rahlgasse 4 — about half a kilometer from the Leopold Museum).

After WW II 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 according to the Trophic State Index (TSI).

Her main interest was the blue-green algae (Cyanophyta) from lakes and rivers, for which she also became a specialist in phycological systematics and corresponded with experts on a worldwide basis.
