Tarihi
Greek historian Olympiodorus of Thebes roasted arsenic sulfide and obtained white arsenic during 5th century AD.
Albertus Magnus is believed to have been the first to isolate the element from a compound in 1250, by heating soap together with arsenic trisulfide.
In 1649, Johann Schröder published two ways of preparing arsenic.
