Geber is the Latinized form of "Jabir", with the full name of Abu Musa Jābir ibn Hayyān al azdi (Arabic: جابر بن حيان‎), (Persian: جابر بن حيان‎) (born c. 721 in Tous–died c. 815 in Kufa), a prominent polymath: a chemist and alchemist, astronomer and astrologer, engineer, geologist, philosopher, physicist, and pharmacist and physician. He is considered by many to be the "father of chemistry." His ethnic background is not clear; although some sources state that he was an Arab, other sources introduce him as Persian. Geber or Jabir is held to be the first practical alchemist.
