Katherine Johnson: How is this for confidence? In 1962, when NASA used computers to calculate John Glenn's orbit around Earth, Glenn had one request: He wanted Katherine Johnson, a West Virginia State University graduate and mathematician, to personally recheck the calculations made by the new electronic computers before his flight aboard Friendship 7 – the mission on which he became the first American to orbit the Earth.

In 1953 Johnson quit her job as a substitute math teacher in Newport News, Va. and took a job at NASA as a “computer," doing analysis on things like gust alleviation for aircraft.

From 1958 until she retired in 1983, she worked as an aerospace technologist.

In 2015 President Barack Obama presented her with a Presidential Medal of Freedom.
