Born in Maryland on November 9, 1731, Benjamin Banneker is often known as the “First African American Scientist.” He built a wooden clock that kept accurate time and worked for over 50 years.

Banneker studied astronomy which is the study of everything in the universe like planets, stars, comets, and galaxies. 

Every year Banneker published an almanac. An almanac is a book that includes a calendar and information about the sun, moon phases, ocean tides, and weather forecasts. Benjamin Banneker’s Almanac was a top seller from Pennsylvania to Virginia and as far as Kentucky from 1792 to 1797.

In 1791, Banneker helped survey the land which is now known as Washington, D.C.
