Google has a video on a history of human computers
presented by David Alen Grier who wrote a book on the subject (When computers were human).
Half way through, I started to feel that the talk was centering too much on the human part of the story but then I realized that the non-human part had been presented by many, many times before so, yes, it is interesting to know who were these people that spend their days writing down calculations.
I especially liked the part where he mentions function tables because it brought me back to my youth when I would browse through the mathematical handbook that my dad had long stopped using and read numbers, the formulas too of course. The numbers where interesting because they are a bit random, which in itself is a facinating concept (if you are young enough!).
The tables of powers of two where also good fun!
Anyways, I found out that human computers where not well respected as the were effectively clerks working under the command of the "planners".
