Geskiendenis
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.

Toepassings
The toxicity of arsenic to insects, bacteria and fungi led to its use as a wood preservative and as insecticides.
Arsenic is used in bronzing, pyrotechny, and for hardening and improving the sphericity of shot.
Gallium arsenide is a semiconductor used in laser diodes and LEDs.
Small amounts of arsenic can be used in lead alloys for ammunition.
