1. Omar Khayyam (1048 - 1131)

With an HPI of 83.47, Omar Khayyam is the most famous Iranian Mathematician.  His biography has been translated into 112 different languages on wikipedia.

Ghiyasoldin Abolfath Omar ebn Ebrahim Khayyam Neyshaburi (18 May 1048 – 4 December 1131), commonly known as Omar Khayyam (Persian: عمر خیّام), was a Persian polymath, known for his contributions to mathematics, astronomy, philosophy, and poetry.: 94  He was born in Nishapur, the initial capital of the Seljuk Empire, and lived during the period of the Seljuk dynasty, around the time of the First Crusade. As a mathematician, he is most notable for his work on the classification and solution of cubic equations, where he provided a geometric formulation based on the intersection of conics. He also contributed to a deeper understanding of Euclid's parallel axiom.: 284  As an astronomer, he calculated the duration of the solar year with remarkable precision and accuracy, and designed the Jalali calendar, a solar calendar with a very precise 33-year intercalation cycle: 659  which provided the basis for the Persian calendar that is still in use after nearly a millennium. There is a tradition of attributing poetry to Omar Khayyam, written in the form of quatrains (rubāʿiyāt رباعیات). This poetry became widely known to the English-reading world in a translation by Edward FitzGerald (Rubaiyat of Omar Khayyam, 1859), which enjoyed great success in the Orientalism of the fin de siècle.

Abū al-Wafāʾ Muḥammad ibn Muḥammad ibn Yaḥyā ibn Ismāʿīl ibn al-ʿAbbās al-Būzjānī or Abū al-Wafā Būzhjānī (Persian: ابو الوفا بوژگانی, Arabic: ابو الوفا بوزجانی; 10 June 940 – 15 July 998) was a Persian mathematician and astronomer who worked in Baghdad. He made important innovations in spherical trigonometry, and his work on arithmetic for businessmen contains the first instance of using negative numbers in a medieval Islamic text. He is also credited with compiling the tables of sines and tangents at 15' intervals. He also introduced the secant and cosecant functions, as well 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.

Abu Nasri Mansur ibn Ali ibn Iraq al-Jaʿdī (Persian: أبو نصر منصور بن علی بن عراق; c. 960 – 1036) was a Persian Muslim mathematician and astronomer. He is well known for his work with the spherical sine law. Abu Nasri Mansur was born in Gilan, Persia, to the ruling family of Khwarezm, the Afrighids. He was thus a prince within the political sphere. He was a student of Abu'l-Wafa and a teacher of and also an important colleague of the mathematician, Al-Biruni. Together, they were responsible for great discoveries in mathematics and dedicated many works to one another. Most of Abu Nasri's work focused on mathematics, but some of his writings were on astronomy. In mathematics, he had many important writings on trigonometry, which were developed from the writings of Ptolemy. He also preserved the writings of Menelaus of Alexandria and reworked many of the Greeks theorems. He died in the Ghaznavid Empire (modern-day Afghanistan) near the city of Ghazna.

His astronomical tables written under the patronage of Sultan Sanjar (Zīj al-Sanjarī, 1115) is considered to be one of the major works in mathematical astronomy of the medieval period.: 107  He provided the positions of fixed stars, and for oblique ascensions and time-equations for the latitude of Marv in which he was based.: 197  He also wrote extensively on various calendrical systems and on the various manipulations of the calendars. Al-Khazini was the author of an encyclopedia on scales and water-balances called The Book of the Balance of Wisdom (Kitab Mizan al-Hikmah, 1121), which explored theories of density, specific gravities of metals, precious stones, and liquids, as well as principles of equilibrium.

Abū Bakr Muḥammad ibn al Ḥasan al-Karajī (Persian: ابو بکر محمد بن الحسن الکرجی; c. 953 – c. 1029) was a 10th-century Persian mathematician and engineer who flourished at Baghdad. He was born in Karaj, a city near Tehran. His three principal surviving works are mathematical: Al-Badi' fi'l-hisab (Wonderful on calculation), Al-Fakhri fi'l-jabr wa'l-muqabala (Glorious on algebra), and Al-Kafi fi'l-hisab (Sufficient on calculation).

7. Abū Sahl al-Qūhī (940 - 1000)

With an HPI of 57.24, Abū Sahl al-Qūhī is the 7th most famous Iranian Mathematician.  Her biography has been translated into 22 different languages.

Abū Sahl Wayjan ibn Rustam al-Kūhī (al-Qūhī; Persian: ابوسهل بیژن کوهی Abusahl Bijan-e Koohi) was a Persian mathematician, physicist and astronomer. He was from Kuh (or Quh), an area in Tabaristan, Amol, and flourished in Baghdad in the 10th century. He is considered one of the greatest geometers, with many mathematical and astronomical writings ascribed to him. Al-Qūhī was the leader of the astronomers working in 988 AD at the observatory built by the Buwayhid amir Sharaf al-Dawla in Badhdad. He wrote a treatise on the astrolabe in which he solves a number of difficult geometric problems. In mathematics he devoted his attention to those Archimedean and Apollonian problems leading to equations higher than the second degree. He solved some of them and discussed the conditions of solvability. For example, he was able to solve the problem of inscribing an equilateral pentagon into a square, resulting in a fourth degree equation. He also wrote a treatise on the "perfect compass", a compass with one leg of variable length that allows users to draw any conic section: straight lines, circles, ellipses, parabolas and hyperbolas. It is likely that al-Qūhī invented the device. Like Aristotle, al-Qūhī proposed that the weight of bodies varies with their distance from the center of the Earth. The correspondence between al-Qūhī and Abu Ishaq al-Sabi, a high civil servant interested in mathematics, has been preserved.

9. Maryam Mirzakhani (1977 - 2017)

With an HPI of 54.75, Maryam Mirzakhani is the 9th most famous Iranian Mathematician.  Her biography has been translated into 80 different languages.

Maryam Mirzakhani (Persian: مریم میرزاخانی, pronounced [mæɾˈjæm miːɾzɑːxɑːˈniː]; 12 May 1977 – 14 July 2017) was an Iranian mathematician and a professor of mathematics at Stanford University. Her research topics included Teichmüller theory, hyperbolic geometry, ergodic theory, and symplectic geometry. On 13 August 2014, Mirzakhani was honored with the Fields Medal, the most prestigious award in mathematics, becoming the first woman to win the prize, as well as the first Iranian. The award committee cited her work in "the dynamics and geometry of Riemann surfaces and their moduli spaces". Mirzakhani was considered a leading force in the fields of hyperbolic geometry, topology and dynamics. Throughout her career, she achieved milestones that cemented her reputation as one of the greatest mathematicians of her time, such as the "magic wand theorem", which tied together fields such as dynamical systems, geometry, and topology. After completing her PhD at Harvard University in 2004, Mirzakhani became a research fellow at the Clay Mathematics Institute and later joined Princeton University as a professor. In 2009, she moved to Stanford University, where she continued her pioneering research until her death. Her work focused on the intricate and complex dynamics of geometric structures, with particular emphasis on moduli spaces and Riemann surfaces. Her approaches and profound insights significantly advanced the field, earning her widespread acclaim and recognition, leading her to win the Fields Medal, the highest honor in mathematics. Born and raised in Tehran, Mirzakhani's passion for mathematics began at a young age. She earned her undergraduate degree from Sharif University of Technology and went on to pursue her PhD at Harvard University under the mentorship of Fields Medalist Curtis T. McMullen. Her academic journey led her to positions at Princeton University and Stanford University, where she became a full professor in 2009. Despite her death at the age of 40 due to breast cancer, her legacy endures through numerous accolades in her honor, including the Maryam Mirzakhani New Frontiers Prize and the 12 May Initiative, both dedicated to promoting women in mathematics.
