(July 1, 965 – March 6, 1040)

Alhazen is regarded as an ingenious icon across the Islamic world. Medieval Europeans nicknamed him “Ptolemy the Second”. Nonetheless, he was Ptolemy’s superior in every aspect of science and mathematics. His works spanned across a wide range of maths and mathematical physics. And they influenced several notable scientists such as Regiomontanus, Nicolaus Copernicus, Johannes Kepler, Isaac Newton, and many others. Alhazen was without question, one of the greatest and prolific scientists of the Middle Ages. His Book of Optics was hailed as the most important work on mathematical physics before Newton’s Principia Mathematica emerged (more than half a millennium later). He also advanced other areas such as: arithmetic, geometry and astronomy. Galileo Galilei, René Descartes and Leonardo da Vinci all borrowed ideas from his works. As an engineer, Alhazen was entrusted with the tasked of remedying the overflowing River Nile in Egypt: during the reign of Fatimid Caliph, Al-Hakim bi-Amr Allah. Although many of his works were lost over the centuries, those that survived indicated that he foraged into fields as diverse as literature, biology, theology, psychology, philosophy, mechanics and medicine. For his role in founding modern science, asteroid 59239 Alhazen and a lunar crater, Alhazen, were named after him.
