A detailrich picture book. Kirkus ReviewsStraightforward and inviting. School Library JournalFrom awardwinning author Lesa ClineRansome and acclaimed illustrator Ral Coln comes the sensitive, informative, and inspiring picture book biography of the remarkable mathematician Katherine Johnson, one of the NASA human computers whose work was critical to the first US space launch.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 trajectories and complex equations to chart the space program. Even as Virginias Jim Crow laws were in place in the early 1950s, Katherine worked analyzing data at the NACA (later NASA) Langley laboratory.In 1962, as NASA prepared for the orbital mission of John Glenn, Katherine Johnson was called upon and John Glenn said get the girl (Katherine Johnson) to run the numbers by hand to chart the complexity of the orbital flight. He knew that his flight couldnt work without her unique skills.President Barack Obama awarded Katherine Johnson the Presidential Medal of Freedom in 2015 and her incredible life inspired the Oscarnominated film Hidden Figures. Get to know this incredible and inspirational woman with this beautifully illustrated picture book from an awardwinning duo.
