In particular the "losers" at the 1927 Solvay Congress -- Schrodinger, Einstein, and de Broglie -- seem to be the antithesis of "shut up and calculate" and all contributed very critical elements of quantum theory.
Schrodinger found the Schrodinger equation, the differential equation that describes so much correctly, through his approach. This is significant because the operator methodology of Heisenberg and Gottingen either did not work, despite the claims it is equivalent to the Schrodinger equation, or was essentially impossible to use to make predictive calculations. Schrodinger's publication of the Schrodinger equation provided an easy way to calculate results in QM that proved correct using well-know differential equations/calculus methods.
For whatever reason, perhaps to keep their research program afloat, the "winners" at the Solvay Congress jettisoned the conceptual underpinnings of Schrodinger's approach and married it to the operator formalism leading to quantum field theory with its intractable infinities and other problems that remain to this day.
