Who created the Borg concept?

Looking at Wikipedia it is clear TNG had already started without the Borg as such, but with the idea that a new powerful adversary was needed.

This article suggests a collective effort in realising the Borg by the writers, but in reality it is usually one or two people who are initially responsible for a concept.

Is there a named person (or persons) responsible for the Borg, such as Gene Roddenberry and Leonard Nimoy were for the Vulcans initially or Branon Braga for Species 8472?

    "Were the Borg inspired by Lord Dread?" I would not call it a duplicate as that question did not ask what I'm asking nor is it clear from a search that it would however the answer to that question answers this question! – user95188 Aug 10 '19 at 17:30
