Yeah, but not UUIDs. Those go back to the 80s.

I think they were invented by Apollo Computer as part of their NCS (Network Computing System). From there, they were adopted by the OSF (later Open Group) DCE RPC system, and from there, by Microsoft (who renamed them GUIDs).

In that vein, earliest mention of UUID I could find (thanks Apollo Archives):

The paper is not dated but probably was around 1986 or later?
