Robert Heilbroner.

On September 10, 1990, multimillionaire socialist author-economist Robert Heilbroner published an article in the New Yorker. It was titled "After Communism." The USSR was visibly collapsing. In it, he recounted the story of the refutation of Mises. In graduate school, he and his peers were taught that Lange had refuted Mises. Then he announced: "Mises was right." Yet in his best-selling textbook on the history of economic thought, The Worldly Philosophers, he never referred to Mises.

Don't you just love that wonderful pairing of words - 'multimillionaire socialist'?
