Here is a fun (albeit slightly sexist) anecdote about “early computers”: 
As N. Katherine Hayles writes in the prologue to My Mother Was a Computer (Hayles, 2005): “in the 1930s and 1940s, people who were employed to do calculations — and it was predominantly women who performed this clerical labor — were called ‘computers.’ (…)”
More after the jump!
In the 1950s, an answer sometimes given to those who feared the growing role of mechanical computers in the workplace was that it would mostly only replace women: human computers and clerical workers.
Christopher Strachey (…) wrote (1954), “(…) Perhaps more important is the fact that there is, in any case, a very large turnover in the clerks they will replace. The majority of these are young women who leave after a few years to get married, so that the introduction of a computer will probably not throw very many people out of work. It will merely stop the intake of new clerks, who will presumably have to seek other occupations. What these will be, is an interesting matter for speculation.”
