An inspiring biography about Katherine Johnson and her incredible aptitude for numbers, boundless curiosity and her early dreams of becoming a research mathematician. Due to the lack of research positions available to women, she became an elementary school teacher. Eventually she landed a job with NASA as a human “computer,” calculating long series of numbers. Katherine is most well known for her integral role in bringing Apollo 13 safely back to Earth. Further information about her life and contributions follow in the book’s back matter.
Counting on Katherine: How Katherine Johnson Saved Apollo 13 was written by Helaine Becker, illustrated by Dow Phumiruk and published by Henry Holt & Co.
