Erno Nemecz

* Losonc, August 22, 1920 – / geochemist, university professor, member of the Hungarian Academy of Sciences (1979) ; ; He completed his secondary school studies in his hometown. In 1938–1942 he studied mineralogy, geology and chemistry at the Pázmány Péter University of Science in Budapest, and obtained his doctoral degree in 1944. In 1943–1944 and then in 1948–1949 he was an assistant professor at the József Nádor Technical University, in 1949–1953 he was an institute professor at the University of Chemical Industry of Veszprém, and between 1953 and 1990 he was the leading professor of the Department of Mineralogy and Crystallography. Since 1990 he has been a professor emeritus. He served as dean of the university in 1953–1954, and as rector in 1971–1980. His research interests include mineralogy, primarily the properties of clay minerals, their geochemistry, X-ray analysis of minerals, and the location of mineral resources. He was the first to describe the large-scale occurrence of clinoptilolite and modernite zeolites in the Tokaj Mountains. He dealt extensively with the structure of clay minerals and the identification of individual mineral types. He developed a new procedure for the mineralogical examination of soils. He participated in the planning of the UNESCO international correlation program (1969). In 1966–1972, he was the editor-in-chief of the Geological Bulletin and at the same time the president of the Hungarian Geological Society. He is a board or honorary member of several international organizations, and an honorary doctor of several foreign universities. ; ; His main works: ; The crystal chemistry of ceramic materials (In: Theoretical foundations of ceramics.
