In her Nuremberg diary, the artist observed, ‘I admire Sir Norman Birkett’s attitude so much - his pity for the twenty wretched creatures in the dock, some of whom know only too well that their days in this world are so few! During the whole of this evening spent at the Birketts’, Sir Norman did not seem able to get the prisoners out of his mind, whatever we talked about. He told me also that however horrible the crime[,] he could never get used to putting on the black cap’ (cited Laura Knight, The Magic of a Line: The Autobiography of Laura Knight, 1965).
