In Margot Lee Shetterly’s book, Hidden Figures, she writes about a cardboard sign on one of the tables in the back of NASA Langley’s cafeteria during the early 1940s that read, “COLORED COMPUTERS.” This particularly struck a nerve with the women because it seemed especially ridiculous and demeaning in a place where research and intellectual ability was focused on much more than skin color. It was Miriam Mann, a member of the West Computers, who finally decided to remove the sign, and when an unknown hand would make a new sign a few days later, Miriam would shove that sign into her purse too. Eventually, the signs stopped reappearing at some point during the war.
I’d have liked to see this in the movie Hidden Figures. (Some more info about Miriam Mann.)
