I remember that the HP2000 system that we used at my high school allowed
a file to be put into a state known as "LOCKED".  This allowed the program
to access data files that were also in a "LOCKED" state and owned by me.
This appears to be essentially the same idea as the SUID bit, and it was
running in 1976.  I guess that since it didn't really change your id to
be the program owner but was a special case in access of files (i.e. such
programs could not create new files owned by the program's owner, etc.)
it isn't quite the same, but the action certainly is awfully close.
