His grandmother taught him to read and write and Banneker studied among black and white students. In 1753, he crafted a perfectly working wooden clock after studying the gears of a pocket watch. This gained him local admiration. He also studied technical books and lunar tables and successfully predicted a lunar eclipse in the year 1789.

Her chemistry career began when she graduated with honors from South Carolina State. She also obtained a master's degree from Howard University. She was one of the first black women to join the FDA. In 1963, Hayden and a group of colleagues were given the task of discovering if Krebiozen was really a cure for cancer. She later discovered that Krebiozen was just creatine and that it couldn't actually cure cancer. Without her, millions of people might have taken a useless drug in hopes of curing cancer.

As a child, she was very interested in astronomy and in high school she became interested in biomedical engineering. In 1973, she began studying at Stanford University where she received degrees in chemical engineering. Jemison applied to NASA and was accepted in 1986. Jemison completed her training as a mission specialist in 1988 and became an astronaut office representative with the Kennedy Space Center in Florida where she began working to process space shuttles for launching. In 1992, Jemison flew into space with six other astronauts aboard the Endeavour, becoming the first African American Woman in space.

He graduated from high school as valedictorian of his class and proceeded to attend the University of Cincinnati. He graduated in 1892 with a B.S. and M.S. degree in biology. In 1907, he earned a Ph.D. in Zoology from the University of Chicago. This made him one of the first African Americans to receive a doctorate in biological sciences. He studied many topics including avian brain structure and aquatic invertebrates. Later he assessed the homing mechanism in ants. He recorded the fact that ants make a type of circle around their nests. This discovery bears his name and is called the Turning Circle. Later in his life and even after he retired, Turner maintained a commitment to civil rights and determined that racism could be studied with eh framework of comparative psychology, and his animal research imitated the existence of different types of racism.

She had a curiosity for numbers and was several grades ahead in school and was just 13 when she was attending high school on the campus of West Virginia State College. She enrolled in the college itself at 18 years old and graduated with honors scores in 1937 and took a job teaching at a black public school in Virginia. In 1961, she did trajectory analysis for Alan Shepard's May 1961 mission Freedom 7 which was American's first human spaceflight. In 1962, Johnson helped NASA prepare for the orbital mission of John Glenn. One of her more notable moments was during the preflight checklist when Johnson did last minute calculations for the launch by hand rather than with a  computer. Glenn's flight was a success and was a major turning point for the competition between the United States and the Soviet Union in space.

Before this invention, many people had damaged hair and skin because they straightened their hair on ironing boards. To increase business for her inventions, Walker organized "Walker Clubs" a system later used by other cosmetic  companies. Walker later became the first African American woman millionaire and employed 3,00 people to her factory in Indiana. She also donated money to the NAACP and funded scholarships for women to go to college.
