One very famous 'human' computer was Edith Clarke , who in addition to being the first professional female electrical engineer in the United States, invented and patented a device called The Clarke Calculator for solving complex infinite series equations involving capacity and inductance in long distance transmission lines for electricity.

Clarke wasn’t satisfied with using error prone assumptions about the characteristics of power lines over 50 miles, however performing the mathematical gymnastics to properly investigate was hard work and extremely time consuming. Her solution was a mechanical slide calculator an engineer could employ to obtain acceptably accurate results in a simplified manner thus avoiding the laborious task of performing such calculations by hand.

Perhaps her most famous quote: "There is no demand for women engineers, as such, as there are for women doctors; but there's always a demand for anyone who can do a good piece of work." -EC
