Hasn’t there been great debate about when the first "stored program" was accomplished? Some said on Maniac by Metropolis but others disagree I think.
I would say that the concept of a process may appear when there are more than one program, potentially ready to execute, and in competition to access the processor.
If that is what you are looking for I am pretty sure it was well before CTSS or Multics. I think CTSS and Multics were in pursuit of time sharing (or multiple stored programs). I think the first implementation of process pipes might have been Demos but that was way after CTSS days.

Yes, it is precisely the kind of entity I am asking about. I would say it appears with CTSS or Multics, but I am not sure. Once I read the name of the creator of the concept, but I did not write it down and I forgot, hence my question.
