>It goes back at least 50 years more, to Star Trek transporters.
Personally, I like to trace this stuff back to early Christian theological debates. Here's an illuminating quotation:
Origen's belief that he could be resurrected in a numerically different body is parallel to Derek Parfit's belief that he could enjoy some kind of survival short of identity, if his present body was destroyed, but the information from it was electronically beamed, so as to construct an exactly similar body and brain with exactly similar psychology at a distance, say on the planet Mars (Reasons and Persons, 199-320). Parfit, like Origen, discounts the need for bodily continuity, and discounts the idea we encountered in Philoponus that it matters whether the original body is replaced gradually, or all at once (op. cit., Appendix D).
