I watched a really interesting documentary about women computers, as they were called. These women were called human computers because they developed the steps and then performed the series of calculations to figure bullet and bomb trajectories. They also were the key programmers on the Eniac, though they got little credit at the time.
The documentary is "Top Secret Rosies" ; I watched it on instant play Netflix, but I think it is widely available.
