A personal Isaac Deutscher story. Back in 58-61, when I was a young Harvard Instructor, I fell in with a circle of junior faculty who gathered around a lovely senior professor named Bob McCloskey, a Canadian legal scholar. One of the group was Zbigniev Bzrezinski, then competing [unsuccessfully, as it turned out] with fellow Russian expert Adam Ulam for one senior slot in the Government Department. [Yes, this is Mika’s father.] One day Deutscher came to Harvard for a visit, and I, along with several others, had lunch with him and Bzrezinski at Adams House. Deutscher had been a member of the Polish Communist Party Central Committee before being ousted for Trotskyite sympathies and emigrating to England. Bzrezinski, who was of course also Polish, was fiercely anti-communist. It was obvious to all of us that the two detested one another, and a tense conversation took place. Then, at one point, Deutscher turned to Bzerzinski and snapped something at him in Polish. It must have been a mortal insult, because Bzrezinski turned white and fell silent, leaving the rest of us to wonder what on earth Deutscher had said.
