The German winegrower Dr. Heinz-Martin Eichelsbacher (1924-2003) studied agriculture at the TH Munich-Weihenstephan. In 1953 he became an employee in the vine breeding department of the Bavarian State Institute and in 1954 technical manager of the State Hofkeller Wuerzburg
whose management he took over in 1969. In 1957 he received his doctorate on the topic "A genetic-breeding comparison of the Vinifera varieties Silvaner, Riesling and Müller-Thurgau". Even then he had doubts about the fatherhood of the Silvaner at Müller-Thurgau
, and assumed that the variety comes from the Riesling-Muskateller-Gutedel variety. His guess was then impressively confirmed around 40 years later. Eichelsbacher has significantly influenced and shaped the development of the Würzburg State Winery with 11 wine-growing companies and 120 hectares of vineyards in Franconia into a commercially run business. He worked as a teacher in the wine-growing school in Veitshöchheim and passed on his extensive knowledge in many publications and specialist articles. In 1987 he was appointed Head of Agriculture and Deputy Head of the Bavarian State Institute for Viticulture and Horticulture. His work "From the royal court cellar to the state winery" is part of the standard viticulture reading.
