Greek mathematician Diophantus of Alexandria also known as Father of Algebra

Diophantus of Alexandria was an Alexandrian Greek mathematician and known as the “father of Algebra”. He is best known for his Arithmetica, a unique collection of 189 algebraic equations and their solutions. Probably born sometime between 201 and 215 AD and died sometime probably between 285 AD and 299AD. He is believed to have lived to be about 84 years

Diophantus did original mathematical work on a variety of problems which can be phrased as single equations or systems of equations, sometimes with a unique solution, sometimes with a finite or infinite family of solutions – although he was content with finding one solution. Diophantus, who seems to have been a Hellenised Babylonian, i.e., someone with a Mesopotamian background but who lived in Alexandrian Greece and who wrote in Greek, is of unsure dates; scholars say that he worked around the year 150 or, more likely, 250.

Qusta ibn Luqa, a Greek christian, worked for the better part of his life as a translator and commentator at the court of Baghdad. He translated Diophantus from Greek into Arabic, probably the first seven books of the Arithmetica. The books IV through VII from this translation resurfaced around 1971 in the Astan Quds Library in Meshed (Iran) in a copy from1198 AD.

Four major contributions:
• Arithmetica (13 Books - only 6 are now Extant)
• Moriastica
• On Polygonal Numbers - of which only fragments now exist
• Porisms
