Shing Tung Yau describes that there was a general skepticism among mathematicians about the Calabi conjecture. He presented a proof that it was false to an informal audience which included Eugenio Calabi. On being contacted by Calabi to write him the arguments. Yau tried to make his assertions rigorous, found a mistake in his own proof, and in trying to correct it, ended up proving it.
This is described in detail by Yau in his book The Shape of Inner Space
