Meet Katherine Johnson, a brilliant mathematician who worked at NASA in the early 1950s until retiring in 1986. Katherine's unparalleled calculations (done by hand) helped plan the trajectories for NASA's Mercury and Apollo missions (including the Apollo 11 moon landing). She is said to be one of the greatest American minds of all time.

"The story of Katherine Johnson, an African American mathematician whose work was critical to the first US space flight"-- Before John Glenn orbited the Earth or astronauts walked on the moon, a group of dedicated female mathematicians known as "human computers" used their knowledge, pencils, adding machines, and writing paper to calculate the orbital mechanics needed to launch spacecraft. Katherine Johnson was one of these mathematicians who used...

"The inspiring autobiography of NASA mathematician Katherine Johnson, who helped launch Apollo 11."-- As a young girl, Katherine Johnson showed an exceptional aptitude for math. In school she quickly skipped ahead several grades and was soon studying complex equations with the support of a professor who saw great promise in her. But ability and opportunity did not always go hand in hand. As an African American and a girl growing up in an era of brutal...
