At the age of sixteen he became an assistant of Samuel Woodburn, the art dealer, and later was employed by Messrs. Hurst, Robinson, & Co., the successors of Boydell, as manager of their print department.
[3] In the course of an enterprising and successful career, throughout which he was recognised as the leading London printseller, Graves published an immense number of fine engravings from pictures by Turner, Wilkie, Lawrence, Constable, Landseer, Faed, Frith, Grant, Millais, and other contemporary painters.
He also issued valuable library editions of the works of Reynolds, Lawrence, Gainsborough, Liverseege, and Landseer.
Graves was one of the founders of The Art Journal and the Illustrated London News, an active member of the Printsellers' Association and the Artists' General Benevolent Fund, and a governor of the Shakespeare memorial at Stratford.
[2] He died at his house on Pall Mall, London, on 23 August 1892, and was buried in Highgate cemetery.
