The Firsts

Elbert Frank Cox was the world's first African-American to receive a Ph.D. in mathematics. Euphemia Haynes was the first African-American woman mathematician to achieve this.

Benjamin Banneker (November 9, 1731 - October 9, 1806)

*Josef Levi*. Seeing his keen interest in the watch, Levi presented it to Banneker. Banneker started examining the watch and its working. He designed huge replicas of the watch by calculating the gear assemblies and made a huge striking clock - the first one to be made completely in America. This invention of Benjamin Banneker served as an accurate timepiece and he earned recognition as a clockmaker. Banneker contributed to the field of astronomy, by devising calculations to predict solar and lunar eclipses.
