Wortmann Julius

The German mycologist and viticulture expert Prof. dr. Julius Wortmann (1856-1925) studied natural sciences in Berlin and Würzburg. In Würzburg he received his doctorate in 1879 with the topic "On the relationship of the intramolecular to the normal respiration of plants". As successor of Dr. Hermann Müller-Thurgau (1850-1927) he was 1891-1903 head of the plant physiological experimental station and 1903-1921 director of the teaching and research institute in Geisenheim, In 1894 he founded the first yeast pure breeding station and led her until 1924. His research focus was the fermentation physiology whose practical significance is related to the quality of the wine odor and taste he recognized early on. He followed his future father-in-law Rudolf Goethe (1843-1911) in the chairmanship of the Prussian Rebenveredlungs commission.
