The Verge has a massive feature on the history and rise of virtual reality which includes this interesting interview with Cory Ondrejka, confirming a belief I had earlier this year:
Cory Ondrejka, the creator of Second Life, is now VP of engineering at Facebook. Ondrejka introduced Mark Zuckerberg to Oculus, and spearheaded Facebook’s acquisition of the up-and-coming company. Now, it’s Ondrejka’s job to help Oculus build out its virtual reality vision as quickly as possible, and distribute it to millions upon millions of people. He spent a few minutes telling us about his virtual dreams — and how they’re being turned into reality.
Cory actually co-created Second Life with Philip Rosedale (along with their small team during Linden Lab's early days), so that's somewhat off. (Source: Some book a guy wrote.) That said, we now it is, as I said, this way: The original vision for Second Life conceived nearly 15 years ago is now coming together at the Internet's largest company.
