I'd just point that, even tough Schrodinger and de Broglie were pretty much focused on understanding, their contribution to quantum theory was very prediction-based, and not so much understanding based. As I said up there, it's not that they believed that, it is that they only got results when working this way. I took Einstein away from your list, there are always exceptions.
What I think is most interesting is that the XX century got an example of each of those "ways of doing science" working. There was probably a "right tool for the job" effect there, as people certainly weren't trying to create a predictive-only theory.
