Jabir ibn
Hayyan, or Geber as he is more commonly known in the Latin west, was, according
to Henderson, the first practical alchemist (11). It has been speculated by many scholars that
Geber, if he existed, did not actually complete most of the works that have
been attributed to him because there is too much disparity in the style and
content of them, but that writers of the Ismaili group may have themselves
created much or all of the work under the Geber pen name (Linden 80). If the Geber of alchemical fame did indeed
exist, it is believed he was born in modern-day Iran around 721 C.E. and
eventually died while under house arrest in Iraq around 815 C.E. (“Abu
Musa”).
