Today, Frank Miles is best known as a friend of Oscar Wilde whom he met at Oxford in 1874 or 1875, where Miles had family connections to the colleges and friends. He was never an undergraduate after being schooled at home, rather than at Eton as his father and uncles were. Miles introduced Wilde to Lillie Langtry, and to his friend and patron Lord Ronald Charles Sutherland-Leveson-Gower, who later became the model for the worldly Lord Henry Wotton in Wilde's 1890 novel "The Picture of Dorian Gray".
