Andreas Marggraf discovered the chemical element zinc in 1746. He isolated zinc by heating calamine (zinc carbonate) with carbon in a closed vessel, leading to the production of pure zinc. This marked an important advancement in the field of chemistry.
German chemist Andreas Sigismund Marggraf is normally given credit for discovering pure metallic zinc in 1746
Glucose was first discovered in the early 19th century by German chemist Andreas Sigismund Marggraf and further analyzed by French chemist Louis Pasteur. It was originally isolated from grapes and termed "grape sugar" due to its abundance in fruits.
Zinc was officially added to the periodic table when Dmitri Mendeleev published his first periodic table in 1869. However, zinc itself was known long before that, having been recognized as a distinct element in the 18th century. It was first isolated by the chemist Andreas Marggraf in 1746.
Andreas Vesalius' book on anatomy, De humani corporis fabrica libri septem (Seven Books on the Fabric of the Human Body) was published in 1543.He didn't discover anatomy, but his work challenged the views of human anatomy set forth by Galen 1300 years prior.
Maltodextrin was discovered in the early 20th century by Russian scientist, Prof. Alexander Samoylovich Marggraf. He developed the process of hydrolyzing starch to create maltodextrin.
Andreas Sigismund Marggraf was born in 1709.
Andreas Sigismund Marggraf died on 1782-08-07.
Andreas Marggraf discovered zinc in 1746 through the process of isolating the metal from calamine ore. He was able to separate zinc oxide from the ore and reduce it to its metallic form by heating with carbon. Marggraf's work was a key development in the understanding and production of zinc.

The element zinc has been used since ancient times, but its discovery as a distinct metal is attributed to Andreas Marggraf, a German chemist, in 1746. Marggraf was able to isolate zinc in its pure metallic form from a calamine ore.

Zinc was first isolated from minerals in 1746 by Andreas Sigismund Marggraf in Brandenburg.
Although zinc compounds have been used for at least 2,500 years in the production of brass, zinc wasn't recognized as a distinct element until much later. Metallic zinc was first produced in India sometime in the 1400s by heating the mineral calamine (ZnCO3) with wool. Zinc was rediscovered by Andreas Sigismund Marggraf in 1746 by heating calamine with charcoal. Today, most zinc is produced through the electrolysis of aqueous zinc sulfate (ZnSO4).
