Hanuš Ettl

Hanuš Ettl (born August 11, 1931 in Prague , † February 22, 1997 in Půlpecen ) was a Czechoslovak botanist and phycologist . The focus of his research was on freshwater algae. He was considered a specialist in flagellate organisms that carry chlorophyll. His botanical author's abbreviation is " H.Ettl ".

Life

Ettl came from a mixed-language family. His mother was Czech and his father was of Austrian descent. He grew up in Šumperk . In 1950 he passed the Matura in Svitavy and began to study botany and phycology at Masaryk University , where Jan Šmarda and Josef Jedlička were his teachers. In 1954, Ettl became Bohuslav Fott's assistant at the Botanical Institute of Charles University in Prague. In 1959 Ettl lost his job for political reasons and then worked as a teacher in Okres Svitavy . At the invitation of the botanist Irene Manton, Ettl worked in 1964 as a visiting scientist at the University of Leeds . In 1966 he accepted an invitation from Hans Pitschmann as a guest at the University of Innsbruck .

In 1968 he was rehabilitated and received his doctorate from Masaryk University in the same year. From 1968 Ettl worked as a research assistant at the Brno branch of the Czechoslovak Academy of Sciences . In 1968 and 1969, two further guest stays at the University of Innsbruck and the Alpine Research Center in Obergurgl followed. In 1974 he was awarded the degree of Candidatus Scientiarum in biological sciences. In 1978 he was not allowed to accept a call from the Philipps University of Marburg as full professor of biology. In 1996 Ettl received a visiting professorship from the University of Innsbruck . In the same year he and Georg Gärtner were awarded the City of Innsbruck Science Prize.

Act

Since the 1950s, Ettl has dealt intensively with the cytology, development history and systematics of flagellates (Volvocales) and hetero accounts (Xanthophyceae). In 1966 he carried out scientific investigations in the moor near Lanser See and the Seefelder Moor near Innsbruck, the Vorderen and Hinteren Finstertaler See and Gossenköllesee in Kühtai and near Obergurgl , which he evaluated in the Alpine Research Center Obergurgl. With the discovery of Chlainomonas rubra (Syn. Sphaerellopsis rubra ) in Canada in 1964 in the red snow (2880 m) below the Sulzkogel, he succeeded in making the first record of this flagellate in the Alps. He named the alga Chlamydomonas obergurglii , which he first described in 1966 , after Obergurgl. In 1976 his main work was published, a 1000-page monograph on the phytomonads Chlamydomonas. Ettl published a total of over 150 publications with a volume of 7,000 pages and was the author or co-author of 13 specialist books.
