The only example I can think of right now is Leonardo Da Vinci inventing the helicopter, but I'm sure there are better examples. These ideas will seem so far out to contemporaries that they die (only to be resurrected by historians after "the helicopter has been invented", so to speak).

So much so, in fact, that Einstein didn't get the Nobel Prize for relativity, but for the photoelectric effect. The irony in that particular story is that he remained unconvinced of quantum mechanics when that showed up later. But he still lived to see common acceptance of relativity. Anyway, the original quote said that a lot of us aren't strong enough to see ideas through, even good ones.
