We probably shouldn't include modern theorists in the list, for example Fred Hoyle, on the grounds that they may still turn out to be correct, or at least more correct than the theory they opposed. (Consider that Hoyle's creation fields theory is very similar to Hubble's Law; if BBT turns out to be false, Hoyle will be remembered by posterity considerably better than he is regarded today in this matter, even if his theories aren't true either.)
