Rolf Rolles is more of a security researcher --- a lot more --- than Daniel Bernstein. But I'll concede it! He's a third.

We're at 3. Do you think I can't name 10 more notable security researchers, justifying each of them, to back up my point here?

I think we'll have to agree to disagree here. But given our different focuses in security, it's not all that surprising that we have different definitions of "security researcher".
