The German naturalist, botanist and doctor of medicine Philipp Jakob Sachs von Löwenheim (1627-1672) studied in Leipzig until the master's degree. Afterwards he visited the most famous universities and physicians of the Netherlands, France and Italy and obtained his doctorate in Padua in 1651 as Dr. med. med. As a result, he operated in the Silesian Wroclaw (now Poland) a medical practice. In 1658 he was admitted to the German Academy of Natural Sciences "Academia Naturae Curiosum". In order to fulfill the requirements of the statute, he wrote a scientific paper and chose a 670-page treatise on the Rebstock out. He called the work published in 1661 " Ampelographia "And thus justified this concept of the theory of the vine, which, however, only 150 years later prevailed.
