Jabir ibn Hayyan c. 721 - 816
Also known as Geber, Jabir ibn Hayyan is considered the father of Islamic chemistry and was a noted alchemist. According to the Library of Congress he was known for his ability to translate complex ideas into simple language so that they could be enjoyed by the public at large and not just the scholarly elite. There is debate as to whether the large number of works attributed to him were actually written by the author or were in fact composed by a number of others.
