Lots of people were involved; Virago, Buckhead and all the others I can't even remember now!

IIRC, Buckhead's post was the first to suggest that the documents were forgeries, then Howlin posted a separate thread about the documents, which helped to get the ball rolling. And lots of freepers chimed in with good analyses. What I think is the coolest is how there's nothing that the document experts pointed out, that hadn't already been pointed out by at least one freeper!
