Katherine Coleman Goble Johnson was born on August 26, 1918 in White Sulphur Springs, WV. She was an American mathematician whose calculations of orbital mechanics as a NASA employee were critical to the success of the first and subsequent U.S. crewed spaceflights. During her 35-year career at NACA/NASA Langley Research Center, she earned a reputation for mastering complex manual calculations and helped pioneer the use of computers to perform the tasks. NASA has noted her "historical role as one of the first African-American women to work as a NASA scientist".

Johnson's work included calculating trajectories, launch windows and emergency return paths for Project Mercury spaceflights, including those for astronauts Alan Shepard and John Glenn, and rendezvous paths for the Apollo Lunar Module and command module on flights to the Moon. Her calculations were also essential to the beginning of the Space Shuttle program. Following her retirement from NASA in 1986, she enjoyed traveling, playing card games, and spending time with her family and friends. She also liked to talk to students about school. She encouraged students to keep studying and to work hard. She told them to learn more about math and science and to never give up on their dreams. In 2015, President Barack Obama awarded Johnson the Presidential Medal of Freedom. In 2016, she was portrayed by Taraji P. Henson as a lead character in the film Hidden Figures. In 2017, NASA Langley Research Center named it's new Computational Research Facility in her honor. And in 2019, Johnson was awarded the Congressional Gold Medal. She passed away in her home in Newport News, VA at the age of 101 on February 24, 2020.
