Diophantus of Alexandria (Ancient Greek: Διόφαντος, romanized: Diophantos) (; fl. 250 CE) was a Greek mathematician who was the author of the Arithmetica in thirteen books, ten of which are still extant, made up of arithmetical problems that are solved through algebraic equations. Although Joseph-Louis Lagrange called Diophantus "the inventor of algebra" he did not invent it; however, his exposition became the standard within the Neoplatonic schools of Late antiquity, and its translation into Arabic in the 9th century AD and had influence in the development of later algebra: Diophantus' method of solution matches medieval Arabic algebra in its concepts and overall procedure. The 1621 edition of Arithmetica by Bachet gained fame after Pierre de Fermat wrote his famous "Last Theorem" in the margins of his copy. In modern use, Diophantine equations are algebraic equations with integer coefficients for which integer solutions are sought. Read more on Wikipedia

His biography is available in different languages on Wikipedia. Diophantus is the 29th most popular mathematician (up from 31st in 2019), the 29th most popular biography from Egypt (up from 33rd in 2019) and the 4th most popular Egyptian Mathematician.

Diophantus is most famous for his work in algebra, where he looked at how to solve polynomial equations of the form ax^2+bx+c=0.
