The US is bigger, and has more first-rank universities, than the UK. So on the plausible hypothesis that the number of people who can be rightly called prominent in a given large community is roughly independent of the size of the community (since I’d expect it to be a matter of how many people one can remember easily) the threshold for prominence in the US should be higher.
(I take it that “prominent” here means something like “with a reasonable chance of being one person a crackpot picks on when s/he goes looking for an academic in the relevant field to contact about his/her crazy theories”. I don’t think this implies “well known to the general public”, though doubtless professors who are well known to the general public get more crank mail.)
I think that it should be strong evidence for ‘better known to the general public than most’, but not strictly implying that, nor good evidence for ‘well known in an absolute sense’ (although that depends on where you draw the line).
