The Swiss botanist, oenologist and Reb breeders Hermann Müller (1850-1927) named himself after his home canton Müller-Thurgau. He first attended the teacher training college and then became a teacher at the secondary school in Stein am Rhein. He then studied in Zurich at today's ETH and graduated in 1872 with the subject teacher diploma for science. After studying at the University of Neuchâtel (Switzerland), he moved in 1872 to the former Botanical Institute of the University of Würzburg, where he received his doctorate in 1874. In the period 1876 to 1890 he worked in a managerial position at the plant physiological research station of the research institute Geisenheim, In 1891 he received a call to the experimental station for fruit, wine and horticulture in Wädenswil, today's Agroscope Changins-Wädenswil whose direction he took over.
He became known mainly by the later named after him new breeding Müller-Thurgau whose final clarification of parenting he no longer experienced, but only much later after decades DNA analysis became possible. But he has also been very successful in other areas. So he led groundbreaking research in the fields physiology the vine, to the phytopathology (plant diseases) of the vine mainly by Botrytis, Wrong mildew and Red burner, In addition, first recognized and explored the connections between climatic conditions and rest periods in vines and fruit trees.
In cellar technology, Hermann Müller-Thurgau explored the possible control of the alcoholic fermentation, the biological degradation of acids (he correctly recognized bacteria as the cause of the malolactic fermentation ) as well as malformations in fermentation and maturation of the wine. He also bred Gärhefestämme with special properties and dealt with methods for the production of non-alcoholic grape juices and for the production of fruit juices. Müller is regarded worldwide as a pioneer in the field of the unfermented pasteurized Fruit juices. His most important publications include noble rot of grapes (1887), The production of unfermented and non-alcoholic fruit and grape wines (1896), The red burner of the vine (1903) and bacteria in wine (1913). The Prof. Müller-Thurgau Prize is awarded as a thank you and recognition to personalities who have rendered outstanding services to the research institute for wine, fruit and horticulture in Geisenheim.
