NASA research mathematician Katherine Johnson is photographed at her desk at Langley Research Center in 1966. Johnson began her career in 1953 at the National Advisory Committee for Aeronautics (NACA), the agency that preceded NASA, one of a number of African-American women hired to work as “computers” in what was then their Guidance and Navigation Department, just as the NACA was beginning its work on space. Johnson became known for her training in geometry, her leadership, and her inquisitive nature; she was the only woman at the time to be pulled from the computing pool to work with engineers on other programs.

Johnson worked at Langley from 1953 until her retirement in 1986, making critical technical contributions which included calculating the trajectory of the 1961 flight of Alan Shepard, the first American in space…

Today, November 24, President Barack Obama awards the Presidential Medal of Freedom, considered the nation’s highest civilian honor, to 17 men and women. Among them is 97-year-old retired African-American NASA mathematician Katherine G. Johnson, selected for her contributions to the space program, starting with the Mercury missions in the ‘50s and early ‘60s, through the Apollo moon missions in the late ’60s and early ‘70s, and ending with the space shuttle missions in the mid ’80s. Among other things, she calculated the trajectories of America’s first manned mission into orbit and the first Moon landing.

Awarding Johnson this well-deserved honor doesn’t just shine a spotlight on a single black female STEM pioneer. It also illuminates an obscure but important piece of history. Johnson was just one of dozens of mathematically talented black women recruited to work as “human computers” at the Langley Memorial Research Laboratory in the ‘40s and ‘50s.

They were so named because before machines came along, they crunched the numbers necessary for figuring out everything from wind tunnel resistance to rocket trajectories to safe reentry angles.

In fact, all of Langley’s hundreds of “human computers,” whether black or white, were women. It was an era when, as Johnson put it, “the computer wore a skirt.”…

WASHINGTON, DC – Today, President Barack Obama named seventeen recipients of the Presidential Medal of Freedom. The Presidential Medal of Freedom is the Nation’s highest civilian honor, presented to individuals who have made especially meritorious contributions to the security or national interests of the United States, to world peace, or to cultural or other significant public or private endeavors. The awards will be presented at the White House on November 24th.

President Obama said, “I look forward to presenting these 17 distinguished Americans with our nation’s highest civilian honor. From public servants who helped us meet defining challenges of our time to artists who expanded our imaginations, from leaders who have made our union more perfect to athletes who have inspired millions of fans, these men and women have enriched our lives and helped define our shared experience as Americans.”

The following individuals will be awarded the Presidential Medal of Freedom:…

Katherine G. Johnson

Katherine G. Johnson is a pioneer in American space history. A NASA mathematician, Johnson’s computations have influenced every major space program from Mercury through the Shuttle program. Johnson was hired as a research mathematician at the Langley Research Center with the National Advisory Committee for Aeronautics (NACA), the agency that preceded NASA, after they opened hiring to African-Americans and women. Johnson exhibited exceptional technical leadership and is known especially for her calculations of the 1961 trajectory for Alan Shepard’s flight (first American in space), the 1962 verification of the first flight calculation made by an electronic computer for John Glenn’s orbit (first American to orbit the earth), and the 1969 Apollo 11 trajectory to the moon. In her later NASA career, Johnson worked on the Space Shuttle program and the Earth Resources Satellite and encouraged students to pursue careers in science and technology fields…
