Andreas Sigismund M arggraf (born 3 March 1709, Berlin; died 7 August
1782, Berlin) was one of the most famous and experimentally adept chemists of
the phlogiston period; his interest in chemistry for its own sake, his refinement of
analytical tools and his use of the balance anticipated some facets of the chemical
revolution and the demise of the phlogiston theory [ 24 c, 79 - 81 ], (see Fig. 2.8 for
his portrait).
He was the son of a court apothecary; from 1725 to 1730, he was a pupil of
Caspar Neumann at the court pharmacy. He later studied at the universities of
Straßburg (now Strasbourg/France) [ 24 V] and Halle/Saale [ 24 IV]. In 1734,
he travelled to Freiberg to the Mining Academy [ 24 VI] to study chemistry with
Henckel and assaying with Süssmilch. In the spring of 1735, he returned to Berlin
to work with his father in the Berlin court pharmacy. In 1738, he became a mem-
ber of the Kurfürstlich Brandenburgische Sozietät der Wissenschaften (Electoral
