Katherine Johnson, legendary NASA mathematician and ‘hidden figure,’ dies at 101

Katherine Johnson, a mathematician who defied prejudice in the ’50s and ’60s to help NASA send the first men to the moon, has died at the age of 101. Only recently famous after the film “Hidden Figures” was made about her and her colleagues, she maintained until the end that she was “only doing her job.”

For those who don’t know Johnson’s story, it is probably best told by reading the book (by Margot Lee Shetterly) or watching the movie — which although it takes some license with the events and persons depicted, is a fascinating and revealing triple portrait of its three protagonists. NASA has also collected numerous historical accounts and anecdotes at a special memorial page.

Johnson and her colleagues struggled unceasingly against racism and sexism, being three women of color attempting to enter an industry which was, and even half a century later remains, dominated by white men. Although Johnson always said her colleagues at NASA were kind and professional, there were nevertheless systematic and deep-seated biases against her at every step of her journey.

After the film’s release and acclaim, she treated her sudden fame with bemusement, happy to be recognized but insistent that she had only been doing her job. Receiving the Presidential Medal of Freedom from President Obama in 2015 was certainly a welcome perk.

But Johnson may have been wary of an over-concentration of credit. She more than anyone would have been aware of the others in similar positions who, while they may not have been quite as instrumental or prominent in the moment — John Glenn famously asked before a flight that a mechanical computer’s calculations be checked by “the girl,” meaning Johnson — were nonetheless indispensable and quite as hidden.

These women, like Johnson’s colleagues Mary Jackson and Dorothy Vaughn, not only challenged the racist and sexist zeitgeist of the time, but very simply helped America achieve what is perhaps its most historically remarkable achievement — the Apollo program — but also to aid in the invention and definition of multiple industries.

Johnson was a remarkable mind and person whose achievements went for too long unnoticed. Had she not been brought into the attention of popular culture, her achievements would likely never have been known outside a few colleagues and historians — and we would all be the poorer for it. Who, and where, are today’s hidden figures, and would we recognize them if we saw them?
