Remembering Presbyterian mathematician, Medal of Honor winner Katherine Johnson

 

A central character in ‘Hidden Figures,’ Johnson was a pioneer in American space history

Katherine Johnson, a mathematician and a longtime Presbyterian Church (U.S.A.) ruling elder who was an important contributor to NASA’s space program, died Feb. 24 at age 101, NASA Administrator Jim Bridenstine announced.

Johnson, a central figure in the book and movie version of “Hidden Figures,” was a longtime member of Carver Memorial Presbyterian Church in Newport News, Virginia. In 2015, President Barack Obama awarded her the Medal of Freedom when she was 97. Obama called her “a pioneer in American space history” and noted the award is 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 Rev. Dr. J. Herbert Nelson, II, Stated Clerk of the General Assembly of the PC(USA), said that Johnson “lived a life of courage that ought to be emulated by all of us who profess a faith in Jesus Christ.”

A NASA mathematician and aerospace technologist from 1953–86, Johnson’s computations have influenced every major space program from the Mercury launches through the space shuttle program. She was hired as a research mathematician at NASA’s Langley Research Center with the National Advisory Committee for Aeronautics, the agency that preceded NASA, after the agency opened hiring to African Americans and women.

She exhibited exceptional technical leadership and is known especially for her calculations of the 1961 trajectory for Alan Shepard’s flight as the first American in space and for her 1962 verification of the first flight calculation made by an electronic computer, in this case for John Glenn, the first American to orbit the Earth.

Johnson said her greatest contribution to space exploration involved the calculations that helped synch the Apollo Lunar Lander with the moon-orbiting Command and Service Module. She also worked on the Space Shuttle and the Earth Resources Satellite and authored or co-authored 26 research reports.

Johnson was born in White Sulphur Springs, West Virginia, in 1918.

By age 13, she was attending the high school on the campus of historically black West Virginia State College. At 18, she enrolled in the college itself, where she made quick work of the school’s math curriculum and found a mentor in math professor W.W. Schieffelin Claytor, the third African American to earn a doctorate in mathematics. Johnson graduated with highest honors in 1937 and took a job teaching at a black public school in Virginia.

When West Virginia decided to integrate its graduate schools in 1939, Johnson and two male students were selected as the first black students to be offered spots in the state’s flagship school, West Virginia University. But she soon left school to start a family, returning to teaching when her three daughters got older.

It wasn’t until 1952 that a relative told her about open positions at the all-black West Area Computing section at Langley, which was headed by fellow West Virginian Dorothy Vaughan.

Johnson was perhaps best known for the work she did in advance of Glenn’s 1962 orbital mission. The complexity of the orbital flight had required the construction of a worldwide communications network, linking tracking stations around the world to computers in Washington, D.C., Cape Canaveral in Florida and Bermuda. The computers had been programmed with the orbital equations that would control the trajectory of the capsule in Glenn’s Friendship 7 mission, from blast off to splashdown. But the Mercury astronauts were wary of putting their lives in the care of the electronic calculating machines, which were prone to hiccups and blackouts. As a part of the preflight checklist, Glenn, like Johnson a Presbyterian, asked engineers to “get the girl” — meaning Johnson — to run the same numbers through the same equations that had been programmed into the computer, but by hand, on her desktop mechanical calculating machine.

“If she says they’re good,” Johnson remembers Glenn saying, “then I’m ready to go.”

Johnson “helped our nation enlarge the frontiers of space,” Bridenstine said in a statement, “even as she made huge strides that also opened doors for women and people of color in the universal human quest to explore space.”
