That's understood in the comment which explicitly indicates that there are many programming circles and that Bellard is known in a number of them (but not all).
eg: I grew up in the Australian Kimberley region (kind of remote), spent decades in geophysical mapping, multi channel data processing, computational algebra, and other odd niches, have no real interest in SV, and am quite familiar with Bellard's work.
Oh, yes. That was a straight-face answer to "who DHH is", not anything to contradict or argue anyone's point. I never heard of the initialism in any other context either.

No idea who DHH is though.
