In September 1913, Henry started at Eton College. During the First World War, Crown Prince Leopold of Belgium, later King Leopold III, was a member of his house (Mr Lubbock's). His studies did not improve, but his nerves and disposition did. He made friends through his enthusiasm for sports, and his masters were very pleased with him, noting in his report that he was "thoroughly willing, cheerful, modest & obedient". To his father, these values were the most important, having no time or interest in what he called "intellectuals".
