As far as I know, the first really explicit depiction of a wife robot built to order may be found in Alice W. Fuller's 1895 story A Wife Manufactured to Order:
"Now, young man, what can I do for you? Want a life-companion, a pleasant one? Man of means, no doubt, and can enjoy yourself; a little fun now and then with the boys and no harm at all -- none in the least... Now, sir, I can get you up any style you want -- wax, but can't be detected."
"Do you mean to say you manufacture a woman out of wax, who will talk?"
"That's just what I do; you give me the subjects you most enjoy talking upon, and tell me what kind of a looking wife you want, and leave the rest to me, and you will never regret it.
