Joseph Nádvornik

Josef Nádvorník (13 February 1906 – 8 July 1977) was a Czech lichenologist. He was an authority on lichens of the order Caliciales and, in particular, the genus Physcia.

Biography Nádvorník was born in Pláňavy on 13 February 1906. After graduating from a burgher school in Hlinsko, he studied at a teacher training institute in Chrudim, from where he graduated in 1925. He started employment as a teacher in Uzhhorod (now Ukraine), working there from the period 1925–1938. With the onset of the German occupation of Czechoslovakia, he was forced to return to the Protectorate of Bohemia and Moravia from where he first started as a teacher, in Hlinsko and later in Prague. With the support and encouragement of lichenologist Miroslav Servít (1886–1959), Nádvorník began collecting and studying lichens, although he did this in his spare time without support financially. In the 1940s he published two important monographs on the lichen families Caliciaceae and Physciaceae. Nádvorník's expertise was on lichens of the order Caliciales and later also on the genus Physcia. He described 5 new genera, 13 sections and 49 species. Nádvorník was the first lichenologist to study and publish lichens from Carpathian Ruthenia. He described the difficult conditions of his lichenological research in a letter to Miroslav Servít. Floristic investigations were undertaken in the Jizera Mountains, Belianske Tatras, and Vysoké Tatry, among other locations in the former Czechoslovakia.…Citește mai mult
