The wine expert Emerich Ráthay (1845-1900) came from a Hungarian noble family and studied at the university in Wien, He was founded by August-Wilhelm in 1874 Babo (1827-1894) to the Klosterneuburg Wine Institute (Lower Austria) professions and taught here the subjects mineralogy, geology, botany, zoology and plant diseases. The focus of his zoological studies was the biology of the phylloxera, of Grape berry moth and the San José scale insect, about which he published extensively. From the 1880s, he dealt with fungal diseases, especially the fake mildew, He also did research on the various flower shapes and seed formation of Vitis vinifera varieties and American vines and pioneered the new breed of grape varieties. In addition, in 1888 he published the work "The gender relations of the vines and their importance for viticulture".
Ráthay also founded chemical research and research activities in Klosterneuburg, From 1870 he treated together with Dr. Leonhard Roesler (1839-1910) in the "Oenochemical Research Station" several topics that were very topical at the time, such as the so-called artificial wine question. After August-Wilhelm Babo retired, he became his successor and headed the institute from 1892 to 1900. A red wine variety created in 1970 in Klosterneuburg was honored in his honor as Rathay named.
