I would love to agree with the sentiment in that quote, but offhand, I can't think of any examples.
Certainly the day-to-day job of the scientist is to prove himself or herself wrong in as many ways as possible, so as not to leave that job to others. But what eventually yields prestige is being right.
One possible counter-example I can think of is the Michelson-Morley experiment, the "most celebrated null experiment in the history of science" to quote one short-breathed biographer. But by several accounts I have read it only became "the most celebrated" thirty-odd years later, once the significance of Einstein's work had sunk in. Before that it seems to have been possible at least to regard it as an anomaly to explain away, for instance via "ether drag" theories.
So even this attempt to prove myself wrong doesn't reach as far as I should hope.
The first person to come to mind for me was Friedrich Ludwig Gottlob Frege who is famous for basically inventing symbolic logic (specifically, predicate logic with quantified variables). He spent an enormous amount of time working on the thesis that the results of mathematics flow rather directly from little more than the rules of logic plus set theory. He aimed to provide a constructive proof of this thesis.
Bertrand Russell discovered a logical flaw (now called Russell's paradox) in Frege's first book containing the constructive proof when the second ...
