Estimate unavailable. StarWorth shows an estimate only when a credible published figure exists — and never invents a number.

Historical figure: wealth claims from this era are speculative, are often repeated in inflated modern equivalents, and cannot be verified — so no estimate is shown for this profile.

Background and career

Abu'l Hassan Ali ibn Ridwan Al-Misri (Arabic: أبو الحسن علي بن رضوان بن علي بن جعفر المصري) (c. 988 - c. 1061) was an Arab who lived in Egypt and was a physician, astrologer and astronomer, born in Giza.

He was a commentator on ancient Greek medicine, and in particular on Galen; his commentary on Galen's Ars Parva was translated by Gerardo Cremonese. However, he is better known for providing the most detailed description of the supernova now known as SN 1006, the brightest stellar event in recorded history, which he observed in the year 1006. This was written in a commentary on Ptolemy's work Tetrabiblos.

He was later cited by European authors as Hali, Haly, or Haly Abenrudian. According to Alistair Cameron Crombie he also contributed to the theory of induction. He engaged in a celebrated polemic against another physician, Ibn Butlan of Baghdad.
