Around the turn of the millennium there were a couple of stories in which mind transfer played a more or less important role.
With mind transfer, I'm referring to the transfer of an individual's mind (soul/consciousness/memories) into a new biological body when the old body is worn out (dying of old age or from wounds), with the new body being custom-made for this individual for this purpose.
Best known examples are probably John Scalzi's Old Man's War series and Battlestar Galactica. (I also remember reading a Star Wars short story where the Emperor used such technology to torture someone to death - being eaten alive by insects, IIRC - as punishment for failure and then transfer the man into a cloned body to continue his work, but I couldn't find that story anymore.)
The earliest occurrence of such mind transfer known to me is Philip Jose Farmer's Riverworld series, published in 1971 but based on an earlier script from the 1950s (that was later published in 1983).
My question: Are there any stories previous to Riverworld that use this concept?
(Bonus question: any other remarkable stories with this concept from the 1980s and 1990s)?
What I'm not looking for:
- Mind swapping of two individuals like in "Dear Pen Pal", SG-1 Episode 39 (2/17) "Holiday", or Buffy Episode 3 (1/3) "Witch" or 72 (4/16) "Who Are You".
- Taking a copy of an individual's memory as a backup, to be inserted into a clone should the person die, but the clone has no knowledge of what happened to the previous instance between the time the backup was created and the person's death. (e.g. in "The Phantom of Kansas")
- Mind uploading into a computer, a network, or a robot.
- Temporal mind transfer and re-transfer like the alternative method of long-distance travel in Dark Matter.
- Surgical, physical transplantation of the brain (or a part of it, like in Wolfgang Hohlbein's Der Thron der Libelle).
The reason for the mind transfer should be that the old body cannot be used any longer (already killed, dying, or severely damaged), not just traveling purpose.
The new body should have been created for the purpose of being the new home for the mind. Take custom made for this individual as desired rather than mandatory; if that new body was one out of thousands of identical new bodies from a mass production, this would be barley within the spirit of the question, while hijacking another living being's body (like in Bingo's answer) is far out.
