Gustav Moesz

* Körmöcbánya, October 21, 1873 – † Budapest, December 8, 1946 / botanist, flora researcher, mycologist, museologist, corresponding member of the Hungarian Academy of Sciences ; ; He began his school studies in Aranyosmarót, then became a student of the Evangelical Lyceum in Selmecbánya, and finally graduated from the Körmöcbánya Realiskola. He enrolled at the Budapest University of Technology, but soon became a student at the University of Science, where he obtained a teaching certificate in 1897. Between 1895 and 1899, he was an assistant professor of mineralogist József Krenner (1839–1920) at the Department of Mineralogy and Petrology, but later his interest increasingly turned towards botany. From 1899 to 1906, he worked as a natural history teacher at the Brasov High School, often collecting plants with his students, and performing microscopic examinations himself. He wrote papers about his observations, supplemented with illustrations made by himself, for the school bulletin (Microscopic flora of the still waters of Brasov, 1902, Algae living in the air and flowing water of the Brasov region, 1904). In 1906, he became a staff member of the Botanical Garden of the National Museum of Natural History and began organizing the mushroom collection. He submitted his doctoral and then habilitation works only at the urging of his superiors, and thanks to this, he obtained the title of private teacher in the field of mycology from 1915. During World War I, he also conducted plant geography observations in Serbia and Poland. During the Soviet Republic of 1919, he was appointed head of department, and for this reason, after the fall of the proletarian dictatorship, he was stripped of his title of private teacher, but he continued his scientific career as a colleague of the MNM Botanical Garden in Budapest, and then as its director from 1929. He retired in 1934, but continued his research and after the end of World War II, he was given back his title of private teacher, and the Hungarian Academy of Sciences elected him a corresponding member. During the war, the mushroom collection of the Botanical Garden was destroyed, which was largely restored thanks to the kindness of Gusztáv Moesz. Of his diverse scientific work, his mycological research stands out primarily: he described 160 species of mushrooms (and 2 flowering plants). He dealt in depth with fungal diseases. He was the editor of the Mycological Bulletins, published as a supplement to the Hungarian Botanical Journals, between 1913 and 1938. Two fungal genera and several plant and animal species were named after him. ; ; His main works: ; Data on the flora of Bars county, 1911, ; Fungi Hungariae I-IV., 1925–1941, ; The fungus of house mushrooms and the fungal growth of buildings, 1934, ; The fungi of Hungary, 1938, ; The flora of the saline areas of Kiskunság and Jászság, 1940, ; Colonized plants, 1941, ; Fungi of Budapest and its surroundings, 1942, ; The fungi of the Carpathian Basin (with Gábor Ubrizsy), 1950.
