H. I have already given Hardy's judgment that Littlewood was the more powerful mathematician of the two: Hardy once wrote that he knew of 'no one else who could command such a combination of insight, technique and power'. Chess problems are the hymn-tunes of mathematics. Mr J. I said that a mathematician was a maker of patterns of ideas, and that beauty and seriousness were the criteria by which his patterns should be judged. Except on special occasions he still did mathematics in the morning, and did not arrive at Fenner's until after lunch. Dining with me one night, he said that he deliberately used to try to get his answers wrong so as to be spared this intolerable ordeal. All the primes of the first class, and none of the second, can be expressed as the sum of two integral squares: thus but 3, 7, 11, and 19 are not expressible in this way (as the reader may check by trial). Money was not a major problem. I sometimes thought he was, for once, less than fair to his colleagues
