Andreas Sigismund Marggraf

Japanese: マルクグラーフ - まるくぐらーふ(英語表記)Andreas Sigismund Marggraf
Andreas Sigismund Marggraf

German chemist. Born to a pharmacist. He studied chemistry, pharmacology, and metallurgy at the highest level of his time in various parts of Germany, and became a member of the Royal Prussian Academy of Sciences in 1738, director of the Academy's chemical laboratory in 1753, and head of the Academy's department of physics and mathematics in 1760. Although he was faithful to the phlogiston theory, he devised excellent experimental methods and made many achievements in the field of analytical chemistry, including the discovery of the increase in weight of phosphorus due to combustion. In 1747, he also extracted sugar from sugar beets and demonstrated that it was the same as sugar from sugar cane, demonstrating the possibility of a sugar beet sugar industry.
