Excerpt:An amusing vignette about Churchill and Isaiah Berlin, from a very long article on Isaiah Berlin.
What to do? As it turned out, the Second World War ensured the question was deferred while Isaiah Berlin spent the next five years working for the British Information Service and Foreign Office in Washington and elsewhere, building up a vast network of useful contacts and a reputation as an incisive researcher and commentator on political, diplomatic and economic issues.
So prominent did his reputation become that he was honored with an invitation to lunch at Downing Street with the Churchills, along with the Commander of the Imperial General Staff and other dignitaries. At the table, the Prime Minister eagerly sought out the views of his special guest on various complex political matters, including the likelihood of Roosevelt being re-elected for a fourth term, but the answers he received seemed not particularly well-informed. He then asked Mr Berlin what he felt was the most important thing he had ever written. “White Christmas,” was the reply. Churchill, perplexed, gave up and turned to someone else. It was only later that he was told that through a mix-up it was the composer Irving Berlin who had been invited to enjoy lunch and Churchill’s company. Ironically, when the story of “the Irving–Winston–Isaiah affair” got out, it further enhanced Isaiah’s reputation, and he found that even more doors in the corridors of power and influence were now open to him.
