He was very, very fond of me, I think it's true to say. He loved to play billiards. He had a billiard table in his room, and I wasn't particularly fond of playing billiards but he would always insist that I come and play and so we would play endless games of billiards, and I think that was just a way of getting me to be in his room. I mean it was - he wanted to, he just loved to have me around and I was certainly very happy because he talked so beautifully about Russia. He was a tremendous patriot. Although he had left Russia somewhere about ten years after the Revolution, he stayed in Leningrad after the Revolution as professor and had been thoroughly in sympathy with the Revolution and wanted the Revolution to work, but then found it was impossible because they imposed all kinds of political conditions on his work. So after ten years he quarreled with the local Communist Party and had to leave the country. But he was always a loyal Russian and even a loyal Soviet supporter. I mean during the war especially he was violently supporting the Soviet government, and he was terribly unhappy because the Western countries weren't doing enough, and the Russians were doing all the fighting in those years.
