I think people are losing sight of the spirit of this thread. It's difficult to argue that the thousands of professional physicists employed by the worlds' universities don't make important contributions to science. They obviously do or they wouldn't be employed.
The distinction I think though, again, being made by the OP, is the qualitative nature of these contributions. In my mind they are what one may refer to as "evolutionary" contributions, meaning that are relatively modest advances on the, pardon the cliche, existing paradigm of the art.
Truly "revolutionary" advances or "quantum leaps" are not typically pioneered by peoples over, say, 30 or 35.
Shrodinger is not a good example. Heisenberg, einstein, Planck, DeBroglie, and Dirac had already done the pioneering work in QM before he developed his equation, beautiful as it was (and still is). However, all he really did was apply the Hamiltonian to the wave equation and follow the logic. Heisenberg and Dirac had already pioneered the core concetual revolution with their matrix model.
