Langton was of a mild, contemplative, enthusiastic nature. When but eighteen years of age he was so delighted with reading Johnson's Rambler that he came to London chiefly with a view to obtain an introduction to the author. Boswell gives us an account of his first interview, which took place in the morning. It is not often that the personal appearance of an author agrees with the preconceived ideas of his admirer. Langton, from perusing the writings of Johnson, expected to find him a decent, well dressed, in short a remarkably decorous philosopher. Instead of which, down from his bed chamber about noon, came, as newly risen, a large uncouth figure, with a little dark wig which scarcely covered his head, and his clothes hanging loose about him. But his conversation was so rich, so animated, and so forcible, and his religious and political notions so congenial with those in which Langton had been educated, that he conceived for him that veneration and attachment which he ever preserved. Langton went to pursue his studies at Trinity College, Oxford, where Johnson saw much of him during a visit which he paid to the university. He found him in close intimacy with Topham Beauclerc, a youth two years older than himself, very gay and dissipated, and wondered what sympathies could draw two young men together of such opposite characters. On becoming acquainted with Beauclerc he found that, rake though he was, he possessed an ardent love of literature, an acute understanding, polished wit, innate gentility and high aristocratic breeding. He was, moreover, the only son of Lord Sidney Beauclerc and grandson of the Duke of St. Albans, and was thought in some particulars to have a resemblance to Charles the Second. These were high recommendations with Johnson, and when the youth testified a profound respect for him and an ardent admiration of his talents the conquest was complete, so that in a "short time," says Boswell, "the moral pious Johnson and the gay dissipated Beauclerc were companions."
