What is Andreas Marggraf known for?

Where did Andreas Marggraf discover glucose?
In 1747, Marggraf announced his discovery of sugar in beets and devised a method using alcohol to extract it. His student Franz Achard later devised an economical industrial method to extract the sugar in its pure form.

What did Andreas Marggraf use to isolate zinc?
Marggraf had isolated zinc in 1746 by heating a mixture of calamine and carbon in a closed vessel without copper. He was unaware that the same process had been developed (and patented) by William Champion in England around 1738–1740 and by Anton von Swab in Sweden around 1742.
What did Andreas Marggraf discover about the sugar industry?

How did Andreas Marggraf contribute to the phlogiston theory?
Although Marggraf noted the weight increase upon the oxidation of phosphorus to form phosphates, he remained the last eminent German adherent of the phlogiston theory, which postulated that a “fire principle” was lost during the combustion or oxidation of substances.
