Katherine Johnson

Katherine Johnson was a NASA "human computer" whose flight-mechanics calculations underpinned Alan Shepard's suborbital flight, John Glenn's orbit of the Earth, and the trajectory of Apollo 11 to the Moon and back.

President Obama awarded her the Presidential Medal of Freedom in 2015.
