While there he met Henry Liverseege, and, perhaps on his advice, went to London at the end of his apprenticeship and entered the studio of William Finden.
[1] About 1838 Stephenson returned to Manchester and established himself as an historical and landscape engraver in Ridgefield, and then in a studio in St. Ann Street.
[1] Stephenson furnished illustrations for Manchester as it is (1839), for Charles Swain's Mind and other Poems, and for other books; and engraved the members' card for the Anti-Corn-law League.
[1] Among Stephenson's later engravings were The Great Day of His Wrath, The Last Judgment, and The Plains of Heaven, after John Martin; The Highland Whiskey Still, the Taming of the Shrew, and The Queen at Osborne, after Edwin Landseer; Ophelia, after John Everett Millais; and the Portrait of Lord Tennyson, after George Frederick Watts.
He also engraved pictures by Daniel Maclise, Gilbert Stuart Newton, Thomas Faed, and Sir John Watson Gordon.
