I’ve nev­er quite under­stood why the phrase “revi­sion­ist his­to­ry” became pure­ly pejo­ra­tive. Of course, it has its Orwellian dark side, but all knowl­edge has to be revised peri­od­i­cal­ly, as we acquire new infor­ma­tion and, ide­al­ly, dis­card old prej­u­dices and nar­row frames of ref­er­ence. A fail­ure to do so seems fun­da­men­tal­ly regres­sive, not only in polit­i­cal terms, but also in terms of how we val­ue accu­rate, inter­est­ing, and engaged schol­ar­ship. Such research has brought us fas­ci­nat­ing sto­ries about pre­vi­ous­ly mar­gin­al­ized peo­ple who made sig­nif­i­cant con­tri­bu­tions to sci­en­tif­ic dis­cov­ery, such as NASA’s “human com­put­ers,” por­trayed in the book Hid­den Fig­ures, then dra­ma­tized in the film of the same name.

Like­wise, the many women who worked at Bletch­ley Park dur­ing World War II—helping to deci­pher encryp­tions like the Nazi Enig­ma Code (out of near­ly 10,000 code­break­ers, about 75% were women)—have been get­ting their his­tor­i­cal due, thanks to “revi­sion­ist” researchers. And, as we not­ed in a pri­or post, we might not know much, if any­thing, about film star Hedy Lamarr’s sig­nif­i­cant con­tri­bu­tions to wire­less, GPS, and Blue­tooth tech­nol­o­gy were it not for the work of his­to­ri­ans like Richard Rhodes. These few exam­ples, among many, show us a fuller, more accu­rate, and more inter­est­ing view of the his­to­ry of sci­ence and tech­nol­o­gy, and they inspire women and girls who want to enter the field, yet have grown up with few role mod­els to encour­age them.
