Philip Emeagwali Philip Emeagwali is the first living mathematician to be celebrated on postage stamps. Philip Emeagwali discovered that the partial differential equations of calculus could be solved across a global network of 65,536 computers. On the foreground were a system of partial differential equations of calculus that were at the mathematical core of the discovery made by Philip Emeagwali. Born: August 23, 1954, Akure, Nigeria More info: Cover story of the May 1990 issue of SIAM News (Society for Industrial and Applied Mathematics) Over 100 Lectures at:

Muḥammad ibn Mūsā al-Khwārizmī The Father of Algebra. The computer term “algorithm” is a corruption of “al-Khwārizmī.” Born: Khwarezm Died: 850 AD, Baghdad, Iraq Books: The Compendious Book on Calculation by Completion and Balancing
Pierre Simon Laplace Contributed to Laplace differential equation. Born: 23 March 1749 in Beaumont-en-Auge, Normandy, France Died: 5 March 1827 in Paris, France
Xiong Qinglai Introduced modern mathematics into China
Born: October 20, 1893, China Died: February 3, 1969
Gottfried Wilhelm Leibniz
Contributed to the development of the differential and integral calculus.
Born: July 1, 1646, Leipzig, Germany Died: November 14, 1716, Hanover, Germany
Blaise Pascal
Contributed to the modern theory of probabilities. Born June 19, 1623, Clermont-Ferrand, France
Died August 19, 1662, Paris
Srinivasa Ramanujan Iyengar Contribution to number theory, infinite series, and continued fractions. Born: December 22, 1887, Erode, India Died: April 26, 1920, Chetput, Chennai, India Books: The lost notebook and other unpublished papers, Collected Papers, Notebooks
Pythagoras Contributed Pythagoras theorem. Born: 571 BC, Samos, Greece Died: Metapontum, Italy
Euclid No true portrait of Euclid exists but we know he lived in a predominately
black city in Africa. Euclid is “The Father of Geometry.” Euclid's text
“The Elements” is the second most reprinted book. It’s second to the
bible. Euclid never travelled outside Africa and it should be assumed that
he is an African that lived on the Nile Valley. Euclidean geometry is the
geometry studied in ancient Africa and modern high school.
Ahmes
Contributed “Ahmes Papyrus,” the oldest mathematical text. Lived during the Second Intermediate Period and the beginning of the Eighteenth Dynasty.
Died: 1620 BC, Egypt
