Of the publishers with whom Byron had a significant association, James Cawthorn was the first, John Hunt the last, and John Murray the one with whom he had the longest involvement. Their status reflected the trajectory of Byron’s career: he began with a small publisher in Cawthorn, was with the influential Murray for the years of his most intense celebrity and allowed the radical Hunt to take over publishing Don Juan when his relationship with Murray broke down. His relationships with these men demonstrate his ambivalence about writing, publishing and commercial success.
