In the first half of the 20th century, the word "computer" meant a person who did heavy-duty computation. During the Second World War and the years following, this included doing the computation for missile development. When the Jet Propulsion Laboratory was created, computers were in great demand there.
And at JPL, something special happened.
Many of the early computers hired there were women.They were working closely with the engineers, who were all men; women were simply not hired as engineers, no matter what their qualifications. The woman who became head of the computer department decided she would only hire women.
