This site is named in honour of Georg Hermann Zschacke (1867-1937), teacher in the Anhaltian town of Bernburg, Germany, who devoted his life to the study of lichens. Besides regional studies on the Harz mountains in Germany, Rumania and the French island of Corse, he published taxonomic studies of Verrucariaceae. A biography (in German) was published by Hermann and Mattick in Verh. Bot. Ver. Prov. Brandenburg 79: 192-195, 196-198 (1939). His herbarum is kept in B.
