Not only a great mathematician but also a civic hero, Katherine Johnson was awarded the Presidential Medal of Freedom by president Barack Obama in 2015 for her extraordinary contribution to the United States' space program. As a celestial navigator for NASA she calculated the trajectories for such historic missions as the Mercury Project and the Apollo 11 mission to the moon.

The subject of the 2017 movie Hidden Figures, Katherine Johnson is an inspiring example to students of mathematics, having overcome both gender bias and racial bias to become one of the most respected figures in American science.

This beautiful poster measures 13 by 19 inches and is printed on heavy, high-gloss paper.
