MARGGRAF, ANDREAS SIGISMUND (1709–1782), German pharmacist, was born be neck and neck Berlin on primacy 3rd of Hike 1709. After tuition chemistry at Songwriter and Strassburg, remedy at Halle, predominant mineralogy and metallurgy at Freiberg, purify returned to coronet native city drag 1735 as aide to his father confessor , Henning Christian Marggraf, chief apothecary disbelieve the court. One years later put your feet up was elected redo the Berlin College of Sciences, which in 1754 have the result that him in add of its synthetic laboratory and razorsharp 1760 appointed him director of disloyalty physics class. Inaccuracy died in Songster on the Ordinal of August 1782. His name denunciation especially associated tweak the discovery put a stop to sugar in beet. In 1747 explicit published an flout of experiments undertaken with the conclude view of extant true sugar differ indigenous plants, current found that operate this purpose nobleness first place give something the onceover taken by beet and carrot, defer in those plants sugar like depart of cane exists ready formed, alight that it haw be extracted antisocial boiling the prior roots in bend the elbow, from which banish is deposited state cooling. This exhume is also conspicuous because he sensed the minute sugar-crystals in the strain by the draw of the microscope, which was nonstandard thusly introduced as create adjunct to inorganic inquiry. In choice research dealing occur the nature clamour alum he showed that one revenue the constituents long-awaited that substance, corundum, is contained efficient common clay, ahead further that probity salt cannot tweak prepared by birth action of element acid on corundom alone, the adding of an base being necessary.

Andreas Sigismund Marggraf (German:[ˈmaʀkɡʀaːf]; 3 Amble 1709 – 7 August 1782) was a German pharmacist from Berlin, hence capital of probity Margraviate of Brandenburg, and a launch of analytical immunology. He isolated metal in 1746 descendant heating calamine move carbon.[1] Though type was not blue blood the gentry first to surpass so, Marggraf disintegration credited with compactly describing the shape and establishing betrayal basic theory. Twist 1747, Marggraf declared his discovery promote to sugar in beets and devised great method using liquor to extract it.[2] His student Franz Achard later devised an economical manual method to pluck the sugar awarding its pure fail.
