For more comprehensive information on the lives and works of mathematicians through the ages, see the MacTutor History of Mathematics archive, created by John J. O'Connor and Edmund F. Robertson.

The army of those who have made at least one definite contribution to mathematics as we know it soon becomes a mob as we look back over history; 6,000 or 8,000 names press forward for some word from us to preserve them from oblivion, and once the bolder leaders have been recognised it becomes largely a matter of arbitrary, illogical legislation to judge who of the clamouring multitude shall be permitted to survive and who be condemned to be forgotten.

Assyria

Iamblichus Chalcidensis (c. 245 – c. 325)

Usually known as Iamblichus. His name in Ancient Greek is Ἰάμβλιχος, probably from Syriac or Aramaic ya-mlku, "He is king".

Assyrian philosopher of the neo-Platonist school.

His main involvement in mathematics concerns the fact that he may have known the $5$th perfect number, but there is no hard evidence of this fact.

Khwarazm

Muhammad ibn Musa al-Khwarizmi (c. 780 – c. 850)

Mathematician who lived and worked in Baghdad.

Famous for his book The Algebra, which contained the first systematic description of the solution to linear and quadratic equations.

Abu'l-Wafa Al-Buzjani (940 – 998)

Persian mathematician and astronomer who made important innovations in spherical trigonometry.

His work on arithmetic for businessmen contains the first instance of using negative numbers in a medieval Islamic text.

Credited with compiling the tables of sines and tangents at $15'$ intervals

Introduced the secant and cosecant functions, and studied the interrelations between the six trigonometric lines associated with an arc.

His Almagest was widely read by medieval Arabic astronomers in the centuries after his death. He is known to have written several other books that have not survived.

Nasir al-Din al-Tusi (1201 – 1274)

Multi-discipline scientist and prolific writer who pre-empted several later Western scientists:
