Something similar happened with me for another theory's article. I knew it existed before the article said. But I only had a primary source to prove it. Since it's not a secondary source I couldn't fix the article, so I put it on the talk page. Now the talk page has been wiped and the article is still wrong about the origin.
Happens frequently. Usually the Wikipedia article is written by the guy who wants to claim credit for an existing design or idea, so he zealously guards the page against the truth. It's just disappointing.
