Benjamin Banneker, born in 1731 and a descendent of African slaves, was a self-taught scientist, mathematician, farmer, astronomer, urban planner—you name it! In 1792, Banneker published the first of eight almanacs, based on his own painstakingly calculated ephemeris (table of the position of celestial bodies), which also included commentaries, literature, and fillers that had a political and humanitarian purpose.

2. Elbert Cox

Dudley Weldon Woodard, born on October 3, 1881 in Galveston, Texas, stood up for civil rights long before Martin Luther King, Jr. made it acceptable. He ignored segregation signs, went into any men’s restroom of his choice, and moved into an all-white community. In 1928, he received his PhD in Mathematics from the University of Pennsylvania, making him the second African-American to earn a PhD in mathematics.

4. Euphemia Lofton Haynes

Euphemia Lofton Haynes became the first African-American woman, and the ninth African-American, to earn a PhD in mathematics. She received hers from The Catholic University of America in Washington, D.C., in 1943. Dr. Haynes then taught in the D.C. school system, and was the first woman to chair the D.C. School Board!

5. Charles Lewis Reason

Few people have the brilliance to be a mathematician and a computer scientist. To top it off, Annie Easley was a rocket scientist! She spent 34 years (1955 to 1985) at NASA, and was influential in making modern space travel possible. She was a leading member of the team that developed software for the Centaur rocket stage, and one of the first African-Americans in her field. Easley’s secret to success? Her mother told her that anything was possible.

8. David Harold Blackwell

    Wow. I had never heard of these brilliant mathematicians until today. As of the time I’m writing this (4/15/13), at least one of these guys don’t even have a Wikipedia article! Their lives need to be celebrated more to encourage the young, black college students today to pursue majors in math and science more.
