Well the comment by pnin made it about GR, when the parent by boringuser2 was about the general contributions to relativity, both SR and GR. I believe "general theory of relativity" to be different than "general relativity" here, the former encompassing both SR and GR. Maybe that's where our misunderstanding comes from. Also, if you believe that GR has absolutely nothing to do with SR, then no Lorentz has no relevance to the genesis of General Relativity.
Anyway I don't believe we're having a discussion worth having here.
My point being: science doesn't happen in a vacuum, and is not totally ordered
