Should have added context to my message but I'm French and lived in France all my life.

If his supposed popularity is coming from a spot on France Culture, I understand why I'm not familiar with him or his work

		I don't want to legitimatize anything but he has been on France Inter, RTL, TF1, France 5, France 3, Canal+, LCI, LCP, Arte, etc. Are you suggesting he isn't actually popular or rather than you do not listen to France Culture or yet something else? I'm a bit confused as it's quite easy to check that he is indeed famous (again, not claiming it has any consequence on this work) in France related to popularizing science. I would bet, but feel free to ask around, that most people interested in scientific popularization know of him, but please do ask around, I'd be curious if it's just in my social circles.
