The quick marketing description of Hidden Figures touts this book as the story of the black women mathematicians of NASA, who helped put men on the moon. But Margot Lee Shetterly’s narrative begins long before that. During World War II, women were entering the workforce in unprecedented numbers, pulled into the vacuum left by men departing to serve in the military. Many of the black women who would go on to play significant roles in the space race began their careers in the segregated West Computing department of the National Advisory Committee for Aeronautics (NACA) on the Virginia Peninsula. In those days, computers were people, not machines, and the insatiable demand for bright mathematical minds cracked the door for black women to enter the agency that would one day become the National Aeronautics and Space Administration (NASA).
