Politician. Foreign Secretary 1905-16. Grey was an important figure in the negotiations which led to the First World War. FH was not impressed by him:
Grey was good-looking, above medium height, slightly but well-built, with a mind that seemed very receptive. In reality, he had no measure of those that talked to him; he accepted Dilke's opinions of South Africa as readily as mine, and when Harold Frederic talked to him of the United States, he accepted some things and rejected others, according to his original conceptions. Consequently he learned nothing valuable. He listened most pleasantly, but I soon found out that he had learned nothing except an argument or two to defend his original view. Grey has one of the closed minds of the world and it is almost as bad as to have no mind at all. I rate him now below almost any of his contemporaries in position.
