The opening as it read in 2005
15th century European portrait of "Geber", Codici Ashburnhamiani 1166, Biblioteca Medicea Laurenziana, Florence Jabir Ibn Hayyan ( ca. 721 , Tus , Iran – 815 , Kufa , Iraq ), full name: Abu Musa Jabir Ibn Hayyan Al-Azdi (أبو موسى جابر بن حيان الأزدي), was an Arab chemist and alchemist. Referred to in Western contexts by the Latinized form of his given name (Jabir), Geber , also known as the Father of Chemistry , because he was the first to scientifically systemize chemistry . Jabir was born in the year 721 CE as the son of a druggist of the famous Arab - Yemeni tribe of Azd . He later became the pupil of the celebrated Islamic teacher Imam Jaffar. He spent most of his life in Kufa, Iraq. In spite of Jabir's leanings toward mysticism and superstition, he more clearly recognized and proclaimed the importance of experimentation . "The first essential in chemistry," he declared, "is that you should perform practical work and conduct experiments, for he who performs not practical work nor makes experiments will never attain the least degree of mastery." He made noteworthy advances in both the theory and practice of chemistry. His books strongly influenced European alchemists and justified their search for the philosopher's stone . He is credited with the invention of many types of now-basic chemical laboratory equipment, and with the discovery and description of many now-commonplace chemical substances and processes — such as the hydrochloric and nitric acids , distillation , and crystallization — that have become the foundation of modern chemistry and chemical engineering . He was a prominent student of Jafar Sadiq . Jabir Ibn Hayyan and Geber were also pen names of an anonymous 14th century European alchemist, author of the treatise Summa Perfectione and several other books: see Pseudo-Geber .1

Persian polymath Abū Mūsā Jābir ibn Hayyān (Arabic/Persian جابر بن حيان , often given the nisbas , al- Azdi , al- Kufi , al- Tusi or al- Sufi ; fl. c. 721 – c. 815), is the supposed author of an enormous number and variety of works in Arabic often called the Jabirian corpus.The scope of the corpus is vast and diverse covering a wide range of topics, including alchemy , cosmology , numerology , astrology , medicine , magic , mysticism and philosophy .Popularly known as the father of chemistry , Jabir's works contain the oldest known systematic classification of chemical substances, and the oldest known instructions for deriving an inorganic compound ( sal ammoniac or ammonium chloride ) from organic substances (such as plants, blood, and hair) by chemical means. As early as the 10th century, the identity and exact corpus of works of Jabir was in dispute in Islamic circles. The authorship of all these works by a single figure, and even the existence of a historical Jabir, are also doubted by modern scholars.Instead, Jabir ibn Hayyan is seen more like a pseudonym to whom "underground writings" by various authors became ascribed.Some Arabic Jabirian works (e.g., the "Book of Mercy", and the "Book of Seventy") were translated into Latin under the Latinized name "Geber", and in 13th-century Europe an anonymous writer, usually referred to as pseudo-Geber , started to produce alchemical and metallurgical writings under this name.

Early Islamic alchemist For other people known as Jabir, see Jabir .Abū Mūsā Jābir ibn Ḥayyān ( Arabic : أبو موسى جابر بن حيّان , variously called al-Ṣūfī , al-Azdī , al-Kūfī , or al-Ṭūsī ), died c. 806−816, is the purported author of an enormous number and variety of works in Arabic, often called the Jabirian corpus.The works that survive today mainly deal with alchemy and chemistry , magic , and Shi'ite religious philosophy.However, the original scope of the corpus was vast and diverse, covering a wide range of topics ranging from cosmology , astronomy and astrology , over medicine , pharmacology , zoology and botany , to metaphysics , logic , and grammar . Jabir's works contain the oldest known systematic classification of chemical substances, and the oldest known instructions for deriving an inorganic compound ( sal ammoniac or ammonium chloride ) from organic substances (such as plants, blood, and hair) by chemical means. His works also contain one of the earliest known versions of the sulfur-mercury theory of metals, a mineralogical theory that would remain dominant until the 18th century.A significant part of Jabir's writings were informed by a philosophical theory known as "the science of the balance" (Arabic: ʿilm al-mīzān ), which was aimed at reducing all phenomena (including material substances and their elements) to a system of measures and quantitative proportions.The Jabirian works also contain some of the earliest preserved Shi'ite eschatological , soteriological and imamological doctrines, which Jabir presented as deriving from his purported master, the Shi'ite Imam Jaʿfar al-Ṣādiq . As early as the 10th century, the identity and exact corpus of works of Jabir was in dispute in Islamic scholarly circles. The authorship of all these works by a single figure, and even the existence of a historical Jabir, are also doubted by modern scholars. Instead, Jabir ibn Hayyan is thought to have been a pseudonym used by an anonymous school of Shi'ite alchemists writing in the late 9th and early 10th centuries.

The c. 215 treatises that survive today mainly deal with alchemy and chemistry , magic , and Shi'ite religious philosophy. However, the original scope of the corpus was vast, covering a wide range of topics ranging from cosmology , astronomy and astrology , over medicine , pharmacology , zoology and botany , to metaphysics , logic , and grammar . The works attributed to Jabir, which are tentatively dated to c. 850 – c. 950 , contain the oldest known systematic classification of chemical substances, and the oldest known instructions for deriving an inorganic compound ( sal ammoniac or ammonium chloride ) from organic substances (such as plants, blood, and hair) by chemical means.
