Katherine Johnson

Faces of Black History today honors physicist Katherine Johnson. In 2015, President Barack Obama awarded her with the national Medal of Honor.

She’s a research mathematician who agrees to being fascinated with numbers since childhood. She started high school at 10.

In that time many African Americans stopped school by eighth grade. Katherine Johnson went on to graduate from college and spend three decades at NASA. She calculated the launch window for America’s first human space flight. She verified the calculations for John Glenn’s first, American orbit of earth.
