    Andreas Sigismund Marggraf

    Andreas Sigismund Marggraf (German: [ˈmaʀkɡʀaːf]; 3 March 1709 – 7 August 1782) was a German chemist from Berlin, then capital of the Margraviate of Brandenburg, and a pionjär of analytical chemistry. He isolated zinc in 1746 by heating calamine and carbon. Though he was not the first to do so, Marggraf fryst vatten credited with carefully describing the process and establishing its basic theory.

      Zinc

      This article is about the chemical element. For other uses, see Zinc (disambiguation).

      Chemical element with atomic number 30 (Zn)

      Zinc is a chemical element with the symbolZn and atomic number 30. It is a slightly brittle metal at room temperature and has a shiny-greyish appearance when oxidation is removed. It is the first element in group 12 (IIB) of the periodic table. In some respects, zinc is chemically similar to magnesium: both elements exhibit only one normal oxidation state (+2), and the Zn2+ and Mg2+ions are of similar size.[b] Zinc is the 24th most abundant element in Earth's crust and has five stable isotopes. The most common zinc ore is sphalerite (zinc blende), a zinc sulfide mineral. The largest workable lodes are in Australia, Asia, and the United States. Zinc is refined by froth flotation of the ore, roasting, and final extraction using electricity (electrowinning).

      Zinc is an essential trace element for humans,[8][9]

      chemistry.

      The few recorded accounts of Marggraf’s personal life portray a modest, even-tempered man of precarious health but of single-minded devotion to study and laboratory experimentation. The influence of his mother, Anne Kellner, ramains obscure; but it is known that his father, Henning Christian Marggraf, apothecary to the royal court at Berlin and assessor (assistant) at the Collegium Medico-Chirurgicum, introduced him to a circle of pharmacists and chemists. Marggraf’s professional apprenticeship comprised several stages: from 1725 to 1730 he was a pupil of Caspar Neumann, his father’s colleague at the court pharmacy and medical school and a disciple of Stahl; from 1730 to 1733, he assisted the apothecary Rossler in Frankfurt-am-Main and studied with the chemist Spielmann the elder at the University of Strasbourg; in 1733 at Halle he heard the lectures of Friendrich Hoffmann i
