After getting his degree Mallory stayed in Cambridge for a year writing an essay he later published as Boswell the Biographer (1912). He lived briefly in France, where Simon Bussy painted his portrait, now in London's National Portrait Gallery. On his return he decided to become a teacher. In 1910 he began teaching at Charterhouse School, Godalming, Surrey, where he met the poet Robert Graves, then a pupil; in his autobiography, "Goodbye to All That", Graves remembered Mallory, who acted as best man at Robert Graves' wedding in 1918, fondly both for his encouragement of Grave's interest in literature in poetry and his instruction in climbing. Graves recalled: "He (Mallory) was wasted (as a teacher) at Charterhouse. He tried to treat his class in a friendly way, which puzzled and offended them."
